Islamic glass is glass made in the Islamic world, especially in periods up to the 19th century. It built on pre-Islamic cultures in the Middle East, especially ancient Egyptian, Persian and Roman glass, and developed distinct styles, characterized by the introduction of new techniques and the reinterpreting of old traditions. [1] It came under European influence by the end of the Middle Ages, with imports of Venetian glass documented by the late 15th century. [2]
It rarely has religious content, other than inscriptions, although the mosque lamp was mainly used in religious contexts, to light mosques, but it uses the decorative styles of Islamic art from the same times and places. The makers were not necessarily Muslims themselves.
Though most glass was simple, and presumably cheap, finely formed and decorated pieces were expensive products, and often highly decorated, using several different techniques. [3] Muhammad disapproved of the use of tableware and drinking vessels made from precious metals, which remained usual for Christian elites in Europe and the Byzantine Empire. Islamic pottery and glass benefited from this, developing luxury styles in the absence of as much competition from ware in other materials, though some Islamic pottery reached the standards required for court entertainments.
The most important centres were Persia, Egypt, Mesopotamia and Syria through most of the period, with Turkey and India later joining them.
Islamic glass did not begin to develop a recognizable expression until the late 8th or early 9th century AD, despite Islam spreading across the Middle East and North Africa during the mid-7th century AD. [4] Despite bringing enormous religious and socio-political changes to the region, this event appears to have not drastically affected the day-to-day workings of craft industries, nor did it cause "extensive destruction or long-lasting disruption". [5] The Byzantine glass industry (Levant and Egypt) and Sassanian (Persia and Mesopotamia) glassmaking industries continued in much the same way they had for centuries, and glass was apparently still exported to the Byzantine Empire from the traditional centres, now under Islamic control. [6] Following the unification of the entire region, the interaction of ideas and techniques was facilitated, allowing for the fusion of these two separate traditions with new ideas, ultimately leading to the Islamic glass industry. [4]
Roman glassmaking traditions that are important in the Islamic period include the application of glass trails as a surface embellishment, while stylistic techniques adopted from the Sassanian Empire include various styles of glass cutting. This may have developed out of the long-standing hardstone carving traditions in Persia and Mesopotamia. [7] [8] In regards to glass-making technology, tank furnaces used in the Levant to produce slabs of raw glass for export during the Classical Period were used during the Early Islamic Period in the same region until the 10th or 11th centuries AD. [9] [10]
During the first centuries of Islamic rule, glassmakers in the Eastern Mediterranean continued to use the Roman recipe consisting of calcium-rich sand (providing the silica and lime) and mineral natron (soda component) from the Wādi el-Natrūn in Egypt, and examples of natron-based Islamic glass have been found in the Levant up to the late 9th century AD. [11] Much Roman glass had apparently begun as enormous slabs made in the Levant, then shipped to Europe for breaking and working. Archaeological evidence has shown that the use of natron ceased, and plant ash became the source of soda for all Islamic glass in the following centuries. [12] [13] [14] [15] The reasons for this technological transition remain unclear, although it has been postulated that civil unrest in Egypt during the early 9th century AD led to a cut-off in the natron supply, thus forcing Islamic glassmakers to look for alternate soda sources. [16]
Evidence of experimentation with the basic glass recipe at Beth She'arim (modern Israel) during the early 9th century AD further supports this argument. A glass slab made from a tank mould from the site contained an excess amount of lime, and may be the result of mixing sand with plant ash. [17] Although the raw glass would have been unusable due to its composition, it does suggest that at this time, Islamic glassmakers in the Levant were combining aspects of Sassanian and Roman traditions in an effort to solve the problem created by the lack of access to mineral natron. The use of plant ash, specifically from halophytic (salt-loving) plants, which were plentiful in the Middle East due to the climate, [18] was well known in Persia and Mesopotamia. It undoubtedly would not take long for the glassmakers in the Near East to correct their manufacturing errors and begin using the plant ash-based recipe used further east.
The glass industry in the Early Islamic Period can initially be characterized as a continuation of older traditions, coinciding with the Umayyad Caliphate, the first Islamic dynasty (Israeli 2003, 319). Following the rise of the Abbasid Caliphate in 750 AD, the capital of the Islamic world was moved from Damascus in the Levant to Baghdad in Mesopotamia. This led to a cultural shift away from the influences of Classical traditions, and allowed for the development of an 'Islamic' expression. [19]
The production of glass during this period is concentrated in three main regions of the Islamic world. Firstly, the Eastern Mediterranean remained a centre of glass production, as it had been for centuries. Excavations at Qal'at Sem'an in northern Syria, [12] Tyre in Lebanon, [20] Beth She'arim and Bet Eli'ezer in Israel, [10] and at Fustat (Old Cairo) in Egypt [21] have all shown evidence for glass production, including numerous vessels, raw glass, and their associated furnaces. In Persia, a formerly Sassanian region, archaeological activity has located a number of sites with large deposits of Early Islamic Glass, including Nishapur, Siraf, and Susa. [22] Numerous kilns suggest Nishapur was an important production centre, and the identification of a local type of glass at Siraf suggests the same for that site. [23]
In Mesopotamia, excavations at Samarra, a temporary capital of the Abbasid Caliphate during the mid-9th century AD, produced a wide range of glass vessels, while work at al-Madā'in (former Ctesiphon) and Raqqa (on the Euphrates River in modern Syria) provide evidence for glass production in the region. [24] [25] However, it is difficult to clearly identify the place in which a glass piece was manufactured without the presence of wastes (pieces broken and discarded in the process of making), which indicate that the location was a site of glassmaking. Furthermore, during the Abbasid caliphate, both glassmakers and their products moved throughout the empire, leading to dispersion of glassware and "universality of style", which further prevents the identification of a piece's birthplace. As the Seljuk empire arose from Seljuk generals conquering lands under the Abbasid flag only nominally, it is likely that glass technology, style, and trade might have continued similarly under the Seljuks as it did under the Abbasids. [26] Despite the increasing ability and style of Islamic glassmakers during this time, few pieces were signed or dated, making identification of a piece's location of origin unfortunately difficult. Glass pieces are typically dated by stylistic comparisons to other pieces from the era. [27]
The majority of the decorative traditions used in the Early Islamic Period concerned the manipulation of the glass itself, and included trail-application, carving, and mould-blowing. [19] As mentioned previously, glass-carving and trail application are a continuation of older techniques, the former associated with Sassanian glassmaking and the latter with Roman traditions. In relief cutting, a specialized form of glass-carving most often used on colourless and transparent glass, "the area surrounding the decorative elements was carved back to the ground, thus leaving the former in relief". [28]
Unlike relief cutting, trail application, or thread trailing, allowed decoration with hot glass. [29] The glassblower would manipulate molten glass while still malleable and create patterns, handles, or flanges. While cutting reached the height of its popularity from the 9th–11th centuries CE, [30] thread-trailing became more widely used during the 11th–12th centuries, when Seljuq glassmakers were considered at the height of their skill. [31]
Mould-blowing, based on Roman traditions from the 1st century CE, is another specialized technique that spread widely throughout the Islamic Mediterranean world during this period. Two distinct types of moulds are known archaeologically; a two-part mould made up of separate halves, and the 'dip' mould, whereby the viscous glass is placed entirely inside one mould. [32] The moulds were often made of bronze, [33] although there are examples of some being ceramic. [34] Moulds also often included a carved pattern; the finished piece would take on the shape and style of the mould (Carboni and Adamjee 2002). With these advances in glassmaking technology, artisans began to stylize and simplify their designs, emphasizing designs with "no foreground or background" and "plain but beautiful vessels". [29]
A final decorative technology that is a distinct marker of the Early Islamic Period is the use of painted lustre decoration. While some scholars see this as a purely Islamic invention originating in Fustat, [35] others place the origins of lustre decoration in Roman and Coptic Egypt during the centuries preceding the rise of Islam. Staining glass vessels with copper and silver pigments was known from around the 3rd century AD, [36] although true lustre technology probably began sometime between the 4th and 8th centuries AD. [37] [38] Lustre painting on glass involves the application of copper and silver pigments, followed by a specific firing that allows for the ionic exchange of Ag+ and Cu+ with the glass, resulting in a metallic sheen fully bound to the vessel. [39] Regardless of its specific origins, lustre decoration was a key technology in glass production that continued to develop throughout the Early Islamic Period, and spread not only geographically, but also to other material industries in the form of lustreware glazed ceramics. [36]
This is the 'Golden Age' of Islamic glassmaking, [40] despite the fractious nature of the Islamic world. Persia and Mesopotamia (along with parts of Syria for some time) came under control of the Seljuq Turks, and later the Mongols, while in the Eastern Mediterranean, the Ayyubid and Mamluk Dynasties held sway. Furthermore, this period saw European interruptions into the Middle East due to the Crusades. [40] [41] Glass production seemingly ceased to exist in Persia and Mesopotamia, and little is known about the reasons for this. [40] However, in the earlier part of this period, there is evidence for glass-making in Central Asia, for example at Kuva in modern Uzbekistan. [42] This tradition presumably ended with the Mongol invasions of the mid-13th century that destroyed other sites in the region. [43]
The glass-producing regions of Syria and Egypt continued their industries. It is for the materials excavated and produced at sites such as Samsat in southern Turkey, [44] Aleppo and Damascus in Syria, [45] Hebron in the Levant, [46] and Cairo [47] [48] that this period is referred to as the 'Golden Age' of Islamic glass. The Middle Islamic Period is characterized by the perfection of various polychrome decorative traditions, the most important of which are marvering, enamelling, and gilding, while relief-carving and lustreware painting seemingly fell out of fashion. [49]
Marvering involves applying a continuous trail of opaque glass (in various colours such as white, red, yellow, or pale blue) around the body of a glass object. This trail may then be manipulated by pulling it, creating a characteristic 'wavy' pattern. The object was then rolled on a marver (a stone or iron slab) to work the trail into the glass vessel itself. [50] This technique, used on a variety of glass objects from bowls and bottles to chess pieces, was introduced around the late 12th century AD, [50] but is in fact a revival of a much older glass-working tradition that has its origins in the Late Bronze Age in Egypt. [51]
Gilding during this period involved applying small amounts of gold in suspension onto a glass body, followed by a low firing to fuse the two materials, and was adopted from Byzantine traditions. [52] Given that gilding individual color enamels have various chemical compositions, a process for firing each color separately was created by Mamluk glass makers. Recognizing that continuously firing and adding different color enamels could result in losing the shape of the original mold. They found that by lowering the temperature and using richer lead enamels it was able to adhere in a single firing.
[53] This technique was often combined with enamelling, the application of ground glass with a colourant, to traditional and new vessel forms, and represents the height of Islamic glassmaking. [54] Enamelled glass, a resurrection of older techniques, was first practiced in the Islamic world at Raqqa (Syria) during the late 12th century, but also spread to Cairo during Mamluk rule. [47]
[55] A study of various enamelled vessels, including beakers and mosque lamps, suggests that there are two subtle yet distinct firing practices, possibly representing two distinct production centres or glass-working traditions. [56] Due to its high demand, enamelled glass was exported throughout the Islamic world, Europe, and China during this period. [57] Enamelling of glass eventually ended in Syria and Egypt following disruption by various Mongol invasions from the 13th through to the 15th centuries AD. [58]
A feature of glass from the Middle Islamic Period is the increased interaction between the Middle East and Europe. The Crusades allowed for the European discovery of Islamic gilded and enamelled vessels. The 'Goblet of the Eight Princes' brought to France from the Levant is one of the earliest examples of this technique. [57] Furthermore, large amounts of raw plant ash were exported solely to Venice, fuelling that city's glass industries. [59] It was also in Venice that enamelling was resurrected following its decline in the Islamic world. [56]
The Late Islamic Period is dominated by three main empires and areas of glass production; the Ottomans in Turkey, the Safavid (and later the Zand and Qajar) Dynasty in Persia, and the Mughals in northern India. [60] The most important over-riding characteristic of glass production in this period is the "direct influence of European glass" and, in particular, that of Venice, Bohemia (in the 18th century), and the Dutch. [61]
The production of high-quality fine glass essentially ended in Egypt, Syria, and Persia, and it was only in India during the 17th century that Islamic glass regained a high level of artistic expression following European influence. [61] [62] The lack of court patronage for glassmaking, as the Ottoman Empire swallowed up most of the Middle East, and the high quality of European glass contributed to a decline in the industry; however, utilitarian glass was still being made in the traditional centres. [60]
Historical documents and accounts, such as the Surname-i Humayun, show the presence of glassmaking, and a glassmaker's guild, in Istanbul, as well as production at Beykoz on the coast of the Bosphorus, in the Ottoman Empire. The glass made at these centres was not of great quality and was highly influenced by Venetian and Bohemian styles and techniques. [63]
In Persia, evidence for glassmaking following the Mongol invasions of the 13th century does not reappear until the Safavid period (17th century). European travellers wrote accounts of glass factories in Shiraz, and it is thought that transplanted Italian craftsmen brought about this revival. [64] No significant decorative treatments or technical characteristics of glass were introduced or revived during this period in Persia. Bottle and jug forms with simple applied or ribbed decoration, made from coloured transparent glass, were common, and are linked to the Shirazi wine industry. [65] The elegant swan-neck bottle for serving wine, began in this period.
Glassmaking in India, on the other hand, saw a return under the Mughal Empire to the enamelling and gilding traditions from the Middle Islamic Period, as well as the glass–carving techniques used in Persia during the earliest centuries of the Islamic world. [66] Glass workshops and factories were initially found near the Mughal capital of Agra, Patna (eastern India), and in Gujarat province (western India), and by the 18th century had spread to other regions in western India. [67]
New forms were introduced using these older Islamic glass-working techniques, and of these, nargileh (water pipe) bases became the most dominant. [68] Square bottles based on Dutch forms, decorated with enamelling and gilding in Indian motifs, are another important expression in Mughal glassmaking, and were produced at Bhuj, Kutch, and in Gujarat. [69] [70] Ethnographic study of current glass production in Jalesar shows fundamental similarities between this site and the Early Islamic tank furnaces found in the Levant, despite differences in the shape of the structures (round in India, rectangular at Bet She'arim), highlighting the technological continuity of the glass industry throughout the Islamic period. [71]
Glass filled a multitude of roles throughout the history of the Islamic world. As with other old glass, most archaeological finds are in fragments, and are plain, undecorated, and utilitarian. [72] Apart from a wide range of open shapes - cups, bowls and dishes, and closed bottle or vase shapes, particular designs include mosque lamps from the Middle Islamic Period, wine bottles from Safavid Persia, and nargileh bases from Mughal India. A variety of vessel forms used to hold a wide range of materials make up the bulk of glass objects (bowls, goblets, dishes, perfume bottles, etc.), and have seen the most attention from Islamic glass scholars. [73]
Some of the more distinct vessel functions from the Islamic period include inkwells (Israeli 2003, 345), qumqum or perfume sprinklers, [74] [75] [76] and vessels associated with Islamic science and medicine such as alembics, test-tubes, and cuppers. [77] [78] [79] [80] Glass was also used for aesthetic purposes in the form of decorative figurines, [81] [82] and for jewellery as bracelets (Carboni 1994; Spaer 1992) and beads. [83] [46] The bracelets, in particular, may prove to be an important archaeological tool in the dating of Islamic sites. [84]

Glass also filled various utilitarian roles, with evidence of use as windows, [85] [86] and as coin weights. These are a distinctive form, very common in Egypt from the 8th century on, of small stamped disks used to check the weight of coins; the earliest known is dated 708–9. [87] [88] [89] The variety of functions filled by glass and the sheer bulk of the material found through excavation further highlights its significance as a distinct and highly developed material industry throughout the Islamic world.
Islamic glass from this period has been given relatively little attention by scholars. One exception to this was the work carried out by Carl J. Lamm (1902–1987). [90] Lamm catalogued and classified the glass finds from important Islamic sites; for example Susa in Iran (Lamm 1931), and at Samarra in Iraq (Lamm 1928). One of the most important discoveries in the field of Islamic glass was a shipwreck dated to around 1036 AD on the Turkey coast at Serçe Liman. The recovered cargo included vessel fragments and glass cullet exported from Syria. [91] The significance of these finds lies in the information they can tell us about the production and distribution of Islamic glass.
Despite this, the majority of studies have concentrated on stylistic and decorative classification (Carboni 2001; Kröger 1995; Lamm 1928; Lamm 1931; Scanlon and Pinder-Wilson 2001), and as such technological aspects of the industry, as well as undecorated vessels and objects, have often been overlooked within the field. This, in particular, is frustrating because the majority of glass finds during the Islamic period are undecorated and used for utilitarian purposes. [72]
Islamic art is a part of Islamic culture and encompasses the visual arts produced since the 7th century CE by people who lived within territories inhabited or ruled by Muslim populations. Referring to characteristic traditions across a wide range of lands, periods, and genres, Islamic art is a concept used first by Western art historians in the late 19th century. Public Islamic art is traditionally non-representational, except for the widespread use of plant forms, usually in varieties of the spiralling arabesque. These are often combined with Islamic calligraphy, geometric patterns in styles that are typically found in a wide variety of media, from small objects in ceramic or metalwork to large decorative schemes in tiling on the outside and inside of large buildings, including mosques. Other forms of Islamic art include Islamic miniature painting, artefacts like Islamic glass or pottery, and textile arts, such as carpets and embroidery.
Glassblowing is a glassforming technique that involves inflating molten glass into a bubble with the aid of a blowpipe. A person who blows glass is called a glassblower, glassmith, or gaffer. A lampworker manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass.
Lustreware or lusterware is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen.
Islamic pottery occupied a geographical position between Chinese ceramics, and the pottery of the Byzantine Empire and Europe. For most of the period, it made great aesthetic achievements and influence as well, influencing Byzantium and Europe. The use of drinking and eating vessels in gold and silver, the ideal in ancient Rome and Persia as well as medieval Christian societies, is prohibited by the Hadiths, with the result that pottery and glass were used for tableware by Muslim elites, as pottery also was in China but was much rarer in Europe and Byzantium. In the same way, Islamic restrictions greatly discouraged figurative wall painting, encouraging the architectural use of schemes of decorative and often geometrically patterned titles, which are the most distinctive and original speciality of Islamic ceramics.
Venetian glass is glassware made in Venice, typically on the island of Murano near the city. Traditionally it is made with a soda–lime "metal" and is typically elaborately decorated, with various "hot" glass-forming techniques, as well as gilding, enamel, or engraving. Production has been concentrated on the Venetian island of Murano since the 13th century. Today Murano is known for its art glass, but it has a long history of innovations in glassmaking in addition to its artistic fame—and was Europe's major center for luxury glass from the High Middle Ages to the Italian Renaissance. During the 15th century, Murano glassmakers created cristallo—which was almost transparent and considered the finest glass in the world. Murano glassmakers also developed a white-colored glass that looked like porcelain. They later became Europe's finest makers of mirrors.
Armanaz is a town in northwestern Syria, administratively part of the Harem District, in the Idlib Governorate. It is located 20 kilometers northwest of Idlib near the Syrian-Turkish borders. Nearby localities include Salqin, Harem and Kafr Takharim to the north and Idlib, Ma'arrat Misrin and Saraqib to the southeast.
Roman glass objects have been recovered across the Roman Empire in domestic, industrial and funerary contexts. Glass was used primarily for the production of vessels, although mosaic tiles and window glass were also produced. Roman glass production developed from Hellenistic technical traditions, initially concentrating on the production of intensely coloured cast glass vessels.
Ancient Chinese glass refers to all types of glass manufactured in China prior to the Qing dynasty (1644–1911). In Chinese history, glass played a peripheral role in arts and crafts, when compared to ceramics and metal work. The limited archaeological distribution and use of glass objects are evidence of the rarity of the material. Literary sources date the first manufacture of glass to the 5th century AD. However, the earliest archaeological evidence for glass manufacture in China comes from the Warring States period.
Forest glass is a type of medieval glass produced in northwestern and central Europe from approximately 1000–1700 AD using wood ash and sand as the main raw materials and made in factories known as glasshouses in forest areas. It is characterized by a variety of greenish-yellow colors, the earlier products often being of crude design and poor quality, and was used mainly for everyday vessels and increasingly for ecclesiastical stained glass windows. Its composition and manufacture contrast sharply with Roman and pre-Roman glassmaking, centered on Mediterranean and contemporaneous Byzantine and Islamic glassmaking to the east. This article is mainly interested in the production of forest glass in Great Britain, though it was also made in other parts of Europe.
Hellenistic glass was glass produced during the Hellenistic period in the Mediterranean, Europe, western Asia and northern Africa. Glassmaking at this time was based on the technological traditions of the Classical antiquity and the Late Bronze Age, but was marked by transition from limited production of luxury objects made for the social elite to mass production of affordable glass vessels used by the broader public to satisfy everyday needs.
Sasanian Glass is the glassware produced between the 3rd and the 7th centuries AD within the limits of the Sasanian Empire of Persia, namely present-day Northern Iraq, Iran and Central Asia. This is a silica-soda-lime glass production characterized by thick glass-blown vessels relatively sober in decoration, avoiding plain colours in favour of transparency and with vessels worked in one piece without over- elaborate amendments. Thus the decoration usually consists of solid and visual motifs from the mould (reliefs), with ribbed and deeply cut facets, although other techniques like trailing and applied motifs were practised.
The ways in which glass was exchanged throughout ancient times is intimately related to its production and is a stepping stone to learning about the economies and interactions of ancient societies. Because of its nature it can be shaped into a variety of forms and as such is found in different archaeological contexts, such as window panes, jewellery, or tableware. This is important because it can inform on how different industries of sections of societies related to each other – both within a cultural region or with foreign societies.
The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, most writers claim that they may have been producing copies of glass objects from Egypt. Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. The earliest known glass objects, of the mid 2,000 BCE, were beads, perhaps initially created as the accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing. Glass products remained a luxury until the disasters that overtook the late Bronze Age civilizations seemingly brought glass-making to a halt.
Hedwig glasses or Hedwig beakers are a type of glass beaker originating in the Middle East or Norman Sicily and dating from the 10th-12th centuries AD. They are named after the Silesian princess Saint Hedwig (1174–1245), to whom three of them are traditionally said to have belonged. So far, a total of 14 complete glasses are known. The exact origin of the glasses is disputed, with Egypt, Iran and Syria all suggested as possible sources; if they are not of Islamic manufacture they are certainly influenced by Islamic glass. Probably made by Muslim craftsmen, some of the iconography is Christian, suggesting they may have been made for export or for Christian clients. The theory that they instead originate from Norman Sicily in the 11th century was first fully set out in a book in 2005 by Rosemarie Lierke, and has attracted some support from specialists.
Byzantine glass objects resembled their earlier Hellenistic counterparts, during the fourth and early fifth centuries CE in both form and function. Over the course of the fifth century CE, Byzantine glass blowers, based mostly in the area of Syria and Palestine, developed a distinct Byzantine style. While glass vessels continued to serve as the primary vehicles for pouring and drinking liquid, glassware for lighting, currency and commodity weights, window panes, and glass tesserae for mosaics and enamels also surged in popularity.
Enamelled glass or painted glass is glass which has been decorated with vitreous enamel and then fired to fuse the glasses. It can produce brilliant and long-lasting colours, and be translucent or opaque. Unlike most methods of decorating glass, it allows painting using several colours, and along with glass engraving, has historically been the main technique used to create the full range of image types on glass.
A. Jennifer Price was an archaeologist and academic, specialising in the study of Roman glass. She was professor emerita in the department of archaeology at Durham University.
Mina'i ware is a type of Persian pottery, or Islamic pottery, developed in Kashan in the decades leading up to the Mongol invasion of Persia and Mesopotamia in 1219, after which production ceased. It has been described as "probably the most luxurious of all types of ceramic ware produced in the eastern Islamic lands during the medieval period". The ceramic body of white-ish fritware or stonepaste is fully decorated with detailed paintings using several colours, usually including figures.
The Nasser D. Khalili Collection of Islamic Art includes 28,000 objects documenting Islamic art over a period of almost 1400 years, from 700 AD to the end of the twentieth century. It is the largest of the Khalili Collections: eight collections assembled, conserved, published and exhibited by the British scholar, collector and philanthropist Nasser David Khalili, each of which is considered among the most important in its field. Khalili's collection is one of the most comprehensive Islamic art collections in the world and the largest in private hands.
The Corning Ewer is an Islamic cameo ewer dating back to around AD 1000. The ewer has been described as "the finest known example of Islamic cameo glass." It is named after The Corning Museum of Glass (CMOG), Corning, NY, it was purchased with funds from the Clara S. Peck Endowment. The Corning Ewer is found in Tehran, Iran. However, the origin of the Ewer is unknown. The Corning Ewer bears close resemblances to The Buckley Ewer and The Rock-Crystal Ewers produced for Fatimid rulers in Cairo, Egypt.
