Laboratory glassware refers to a variety of equipment used in scientific work, and traditionally made of glass. Glass can be blown, bent, cut, molded, and formed into many sizes and shapes, and is therefore common in chemistry, biology, and analytical laboratories. Many laboratories have training programs to demonstrate how glassware is used and to alert first–time users to the safety hazards involved with using glassware.
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.
Millefiori is a glasswork technique which produces distinctive decorative patterns on glassware. The term millefiori is a combination of the Italian words "mille" (thousand) and "fiori" (flowers). Apsley Pellatt in his book Curiosities of Glass Making was the first to use the term "millefiori", which appeared in the Oxford English Dictionary in 1849; prior to that, the beads were called mosaic beads. While the use of this technique long precedes the term "millefiori", it is now most frequently associated with Venetian glassware.
Cobalt glass—known as "smalt" when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour.
The crowns of Silla were made in the Korean kingdom of Silla approximately in the 5th–7th centuries.
Bakewell Glass is nineteenth-century glassware from Pittsburgh, Pennsylvania, produced by a company founded by Benjamin Bakewell. Bakewell's company can be found under the names ThePittsburgh Glass Manufactory, Bakewell & Page and, Bakewell, Pears & Co. Bakewell glass built a reputation of being both luxurious and utilitarian during the 80 years it was in business.
The firm of James Powell and Sons, also known as Whitefriars Glass, were London-based English glassmakers, leadlighters and stained-glass window manufacturers. As Whitefriars Glass, the company existed from the 17th century, but became well known as a result of the 19th-century Gothic Revival and the demand for stained glass windows.
Bohemian glass, also referred to as Bohemia crystal, is glass produced in the regions of Bohemia and Silesia, now parts of the Czech Republic. It has a centuries long history of being internationally recognised for its high quality, craftsmanship, beauty and often innovative designs. Hand-cut, engraved, blown and painted decorative glassware ranging from champagne flutes to enormous chandeliers, ornaments, figurines and other glass items are among the best known Czech exports and immensely popular as tourist souvenirs. The Czech Republic is home to numerous glass studios and schools attended by local and foreign students.

Royal Leerdam Crystal was a Dutch producer of glassware products based in Leerdam, the Netherlands.
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. However, during the 1st century AD the industry underwent rapid technical growth that saw the introduction of glass blowing and the dominance of colourless or 'aqua' glasses. Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels, and by the end of the 1st century AD large scale manufacturing resulted in the establishment of glass as a commonly available material in the Roman world, and one which also had technically very difficult specialized types of luxury glass, which must have been very expensive.
The Art & History Museum is a public museum of antiquities and ethnographic and decorative arts located at the Parc du Cinquantenaire/Jubelpark in Brussels, Belgium. The museum is one of the constituent parts of the Royal Museums of Art and History (RMAH) and is one of the largest art museums in Europe. It was formerly called the Cinquantenaire Museum until 2018. It is served by the metro stations Schuman and Merode on lines 1 and 5.
The influence of the Islamic world to the history of glass is reflected by its distribution around the world, from Europe to China, and from Russia to East Africa. Islamic glass developed a unique expression that was characterized by the introduction of new techniques and the reinterpreting of old traditions.
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.
Conservation and restoration of glass objects is one aspect of conservation and restoration of cultural heritage. The nature and varying composition of the material, and the variety of types of object made from it, demand certain specialized techniques. The conservator needs to be aware of "agents of deterioration" presenting particular risk to glass objects, and how to prevent or counteract their effects. Relevant education and training is available in certain countries through museums, conservation institutes and universities.
Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware.
Byzantine glass objects highly 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. Following the Arab conquests of the seventh century CE, large quantities of glass were imported from the Levant, which continued to produce raw and manufactured glass. Scholars once believed that glassware was an expensive luxury good reserved for the upper strata of society, however, recent archaeological excavations have unearthed a considerable quantity of unadorned glassware intended for lower-class residents.
An Jiayao is a Chinese archaeologist and the director the Xi’an Research Program and the Han & Tang Research Program of the Archaeology Research Institute under the Chinese Academy of Social Sciences (CASS). She is a specialist in the ancient glass of China, Central Asia, and the Near East and has additional interests in Sui and Tang dynasty Buddhist temples, the Taiye Lake ruins at the Tang dynasty Da Ming Palace, and the preservation and exhibition of archaeological sites. She received her MA in 1982 from Archaeology Department of CASS and has been involved in numerous excavations. From 2001 to 2005, she led an excavation at the imperial gardens at Daming Palace's Taiye Pond in a joint project between CASS's Institute of Archaeology and Japan's Nara National Research Institute for Cultural Properties. In 2014, she received a letter of appointment to membership in the Central Research Institute of Culture and History from Premier Li Keqiang. As deputy leader of the World Heritage Expert Group at the State Administration of Cultural Heritage, she also helped submit applications to UNESCO for the Anyang Yin Ruins, the West Lake in Hangzhou, and the Site of Xanaduto to become World Heritage Sites.
