Sulphide portrait glassware is blown, cut, and molded glassware usually made from lead crystal that encases an image. The image appears silver or white, as if made from silver sulphide. Although sulphide is used to describe glass decorated in this manor, the silver or white image is actually a hardened clay paste. Experiments with this glass decorating style began in Europe during the late 18th century, and processes for production were successfully implemented in France and England during the early 19th century. Production in the United States began in the 1820s.
Pittsburgh glass manufacturer Bakewell, Page and Bakewell was the first major manufacturer of sulphide portrait glassware in the United States. During the 1820s, sulphide portrait glassware ornamentation style was known as cameo–incrustation or crystallo ceramie. This type of glassware became popular again during the middle of the 19th century. Bakewell, Page and Bakewell used an unusual style for their sulphide portrait tumblers. The portrait was at the bottom of the tumbler, while the sides of the ware featured engravings. The men portrayed in these tumblers were famous historical figures, such as Marquis de Lafayette, George Washington, and Benjamin Franklin. Also portrayed were then current politicians that were champions of causes that favored the domestic glass producing industry, such as Andrew Jackson and DeWitt Clinton.
In the glass industry, a sulphide is a glass object that contains an image encased in the glass that appears as white porcelain. [1] These images can also appear to be silver. [2] Inserting the object, or cameo, into the glass was the most difficult part of the production process. There could be no air bubbles between the cameo and the glass. The cameo needed to be white, which could give it a silvery appearance when viewed through the glass. [3] Historians at the end of the 19th century speculated that the silvery objects encased in glass were made of silver sulphide, although the objects were actually made of a clay paste. The name "sulphide", although not correct, has continued to be the term used to describe glass decorated using this method. [4]
Glassmakers in Bohemia are thought to have unsuccessfully experimented with sulphide production during the late 18th century. This may have occurred as early as 1750, although one source uses "about 1780". [5] No examples of the Bohemian experimentation have been found that date before 1798. [4] In the early 19th century, a French medallion maker began encasing his product in glass, and a similar product was made in England at about the same time. [2] Sulphide portrait glassware was most popular between 1815 and 1830. At the time, the objects were described as cameo–incrustation or crystallo ceramie. [4] During the first 30 years of the 19th century, French sulphides were typically exported to Germany and Austria, while the majority of sulphide portrait glassware found in America or England was manufactured in England. Lower quality imitations caused a decline in popularity. [6]
The process for making a sulphide was developed in France by Barthélemy Desprez early in the 19th century. [2] [Note 1] Originally a chemist at the French porcelain company Manufacture nationale de Sèvres, Desprez made the "finest sulphides". [8] Desprez was employed at Sèvres from 1773 until 1783, and from 1786 to 1792. His job titles were modeler, chief modeler, and supervisor of the preparation of porcelain bodies. His son, Barthélemy Desprez Jr., was also involved with cameo portraits in glass. [7] Another early French creator of sulphide portrait glassware, who also worked at one time at Sèvres, was the Chevalier de Saint-Amans (Pierre Honoré Boudon de Saint-Amans). [9] Saint-Amans received a French patent in 1818 for improving (not creating) the process for encrusting cameos in glass. [10] An 1850 report credits Saint-Amans with producing "marvels of artistic beauty". [11]
In England, ceramic portrait medallions made by Josiah Wedgwood created interest in the production of portraits encased in glass. [4] Wedgwood was a potter who was one of the first to industrialize pottery manufacturing, and he was also credited with inventing modern marketing. [12] Glassmaker Apsley Pellatt received an English patent for the sulphide process in 1819. His sulphides were typically medallions or paperweights. They could also be set in plaques of glass to be hung on a wall. Some sulphide portraits were added to the sides or the bottoms of glassware such as tumblers, beakers, and bottles. [2] Pellatt's cameos consisted of china clay, sand, and potash that were cast in molds and then heated to a hardness so the clay mixture would withstand encasement in glass. [3] The Pellatt family ran London's Falcon Glass Works, and it has been described as the "pre-eminent London glassmaking factory of the 19th century". [13] Pellatt produced sulphide portrait glassware from the 1820s until the 1850s. He died in 1863. [14]
Benjamin Bakewell moved to New York from London in 1793. In London he had been an importer of luxury goods, and he started the same type of business in his new home city. [15] Because of his occupation, Bakewell was very familiar with French and English fashions and styles. [16] In 1808 Bakewell ended his import business and began a glass factory in Pittsburgh, and beginning September 1, 1813, his glass-making business was renamed Bakewell, Page and Bakewell. [17] [Note 2] Bakewell employed English and French glassmakers, and chose to compete with high-quality European glass companies. A decade later, he was producing one of the "most fashionable and difficult" objects of European glass ornamentation: sulphide portrait glassware. [16]
In 1824, Marquis de Lafayette began a tour of the United States. Lafayette had achieved fame from his service in the Continental Army during the American Revolutionary War. His visit to Pittsburgh during May 1825 included a tour of Bakewell's glass works. [20] Aware of European sulphide portrait glassware and capitalizing on Lafayette's popularity, Bakewell produced both commemorative tumblers and tumblers with a sulphide portrait of Lafayette in its base. [21] [Note 3] A sulphide portrait tumbler was also produced of Senator (and future president of the United States) Andrew Jackson, commander of American troops in the Battle of New Orleans during the War of 1812. [24] Jackson was an opponent of John Quincy Adams for president of the United States, and Adams' policies were not considered favorable to manufacturers. [25] Other sulphide glassware known to have been made by Bakewell included images of George Washington, Benjamin Franklin and DeWitt Clinton. [26] Clinton was a champion of transportation infrastructure projects such as the Erie Canal, which benefited glass producers by lowering transportation costs. [27]
The American production of sulphide portrait glassware is thought to have ended a few years after 1825, and Bakewell is the only American company known to have produced it in significant quantities during that period. Bakewell's major rival, New England Glass Company, did not advertise anything similar. Sulphide glassware remained popular in Europe, but did not revive in the United States until the 1850s. There is no evidence that Bakewell was involved in sulphide portrait glassware in the 1850s, and sulphide portrait bottles and paperweights from that period are thought to have been produced by factories from New England and New Jersey.

Josiah Wedgwood was an English potter, entrepreneur and abolitionist. Founding the Wedgwood company in 1759, he developed improved pottery bodies by systematic experimentation, and was the leader in the industrialisation of the manufacture of European pottery.
Cameo is a method of carving an object such as an engraved gem, item of jewellery or vessel. It nearly always features a raised (positive) relief image; contrast with intaglio, which has a negative image. Originally, and still in discussing historical work, cameo only referred to works where the relief image was of a contrasting colour to the background; this was achieved by carefully carving a piece of material with a flat plane where two contrasting colours met, removing all the first colour except for the image to leave a contrasting background.
A paperweight is a small solid object heavy enough, when placed on top of papers, to keep them from blowing away in a breeze or from moving under the strokes of a painting brush. While any object, such as a stone, can serve as a paperweight, decorative paperweights of metal, glass, jade or other material are also produced, either by individual artisans or factories.
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.
Blenko Glass Company is an art glass company that began producing in 1922 under the name Eureka Art Glass Company. The company name was changed to Blenko Glass Company in 1930. Originally an antique flat glass company, it was founded by Englishman William J. Blenko (1854-1933). Blenko came to the United States to make glass in 1893. Over the next 25 years, he established glass factories in Indiana, Pennsylvania, and West Virginia—which all failed. His fourth glass factory, that began production in 1922, was a success and still operates today (2024). This factory is located in Milton, West Virginia, and Blenko family members still lead the company.
The "Marlborough gem" is a carved onyx cameo that depicts an initiation ceremony of Psyche and Eros. It is the most famous engraved gem in the extensive and prominent collection both inherited and expanded by George Spencer, 4th Duke of Marlborough. Since 1899 it has been in the collection of the Boston Museum of Fine Arts, where it is described as a "cameo with the wedding of Cupid and Psyche, or an initiation rite", reflecting the view of its subject generally held until the last century.
Apsley Pellatt was an English glassware manufacturer and politician.
Gold glass or gold sandwich glass is a luxury form of glass where a decorative design in gold leaf is fused between two layers of glass. First found in Hellenistic Greece, it is especially characteristic of the Roman glass of the Late Empire in the 3rd and 4th century AD, where the gold decorated roundels of cups and other vessels were often cut out of the piece they had originally decorated and cemented to the walls of the catacombs of Rome as grave markers for the small recesses where bodies were buried. About 500 pieces of gold glass used in this way have been recovered. Complete vessels are far rarer. Many show religious imagery from Christianity, traditional Greco-Roman religion and its various cultic developments, and in a few examples Judaism. Others show portraits of their owners, and the finest are "among the most vivid portraits to survive from Early Christian times. They stare out at us with an extraordinary stern and melancholy intensity". From the 1st century AD the technique was also used for the gold colour in mosaics.
Seneca Glass Company was a glass manufacturer that began in Fostoria, Ohio, in 1891. At one time it was the largest manufacturer of blown tumblers in the United States. The company was also known for its high-quality lead (crystal) stemware, which was hand-made for nearly a century. Customers included Eleanor Roosevelt and Lyndon B. Johnson, and retailers such as Marshall Field and Company, Neiman Marcus, and Tiffany's.
Early glassmaking in the United States began in Colonial America in 1608 at the Colony of Virginia near Jamestown, believed to be the first industrial facility in what would later become the United States. For centuries, glassmaking procedures, techniques, and recipes were kept secret, with countries actively preventing glassmaking knowledge from spreading beyond their borders. German workers with glassmaking knowledge, described as Dutchmen, along with Polish glass workers, were brought to Colonial America to begin operations. Although glass was made at Jamestown, production was soon suspended because of strife in the colony. A second attempt at Jamestown also failed.
J. H. Hobbs, Brockunier and Company was one of the largest and best-known manufacturers of glass in the United States during the 19th century. Its products were distributed worldwide. The company is responsible for one of the greatest innovations in American glassmaking—an improved formula for lime glass that enabled American glass manufacturers to produce high-quality glass at a lower cost. The firm also developed talented glassmakers that started glass factories in Ohio and Indiana.
Indiana Glass Company was an American company that manufactured pressed, blown and hand-molded glassware and tableware for almost 100 years. Predecessors to the company began operations in Dunkirk, Indiana, in 1896 and 1904, when East Central Indiana experienced the Indiana gas boom. The company started in 1907, when a group of investors led by Frank W. Merry formed a company to buy the Dunkirk glass plant that belonged to the bankrupt National Glass Company. National Glass was a trust for glass tableware that originally owned 19 glass factories including the plant in Dunkirk. National Glass went bankrupt in 1907, and its assets were sold in late 1908.
The Wedgwood anti-slavery medallion was an abolitionist symbol produced and distributed by British potter and entrepreneur Josiah Wedgwood in 1787 as a seal for the Society for the Abolition of the Slave Trade. The medallion depicts a kneeling black man in chains with his hands raised to the heavens; it is inscribed with the phrase "Am I not a man and a brother?"
18th century glassmaking in the United States began before the country existed. During the previous century, several attempts were made to produce glass, but none were long-lived. By 1700, it is thought that little or no glass was being produced in the British colonies that would eventually become the United States. The first American glass factory operated with long–term success was started by Caspar Wistar in 1745—although two glass works in New Amsterdam that operated in the previous century deserve honorable mention. Wistar's glass works was located in the English colony known as the Province of New Jersey. In the southeastern portion of the Province of Pennsylvania, Henry Stiegel was the first American producer of high–quality glassware known as crystal. Stiegel's first glass works began in 1763, and his better quality glassmaking began in 1769. In the United States, the first use of coal as a fuel for glassmaking furnaces is believed to have started in 1794 at a short-lived factory on the Schuylkill River near Philadelphia. In 1797 Pittsburgh's O'Hara and Craig glass works was also powered by coal, and it contributed to the eventual establishment of Pittsburgh as a leading glassmaking center in the 19th century.
Very few 19th Century glassmaking innovations in the United States happened at the beginning of the century. Only ten glass manufacturers are thought to have been operating in 1800. High-quality glassware was imported from England, and glassmaking knowledge was kept secret. England controlled a key ingredient for producing high–quality glassware and kept its price high—making it difficult for American glass manufacturers to compete price-wise. European glassmakers with the knowledge to produce high–quality glassware were, in some cases, smuggled to the United States. Eventually the American glass industry grew, and the second half of the century saw numerous innovations.
19th century glass categories in the United States include types of glass and decoration methods for glass. A simplified category version appropriate at the beginning of the century is glassware, bottles, and windows. As the century progressed, glass production became more complex and made necessary more categories and subcategories. An 1884 United States government report used glassware, bottles, windows, and plate glass as major categories—although plate glass accounted for only four percent of the value of all glass made.
19th century glassmaking in the United States started slowly with less than a dozen glass factories operating. Much of the nation's better quality glass was imported, and English glassmakers had a monopoly on major ingredients for high–quality glass such as good–quality sand and red lead. A tariff and the War of 1812 added to the difficulties of making crystal glass in America. After the war, English glassmakers began dumping low priced glassware in the United States, which caused some glass works to go out of business. A protective tariff and the ingenuity of Boston businessman Deming Jarves helped revive the domestic glass industry.
Bakewell, Pears and Company was Pittsburgh's best known glass manufacturer. The company was most famous for its lead crystal glass, which was often decorated by cutting or engraving. It also made window glass, bottles, and lamps. The company was one of the first American glass manufacturers to produce glass using mechanical pressing. In the 1820s and 1830s, Bakewell glassware was purchased for the White House by presidents James Monroe and Andrew Jackson. Founder Benjamin Bakewell is considered by some to be father of the crystal glassware business in the United States.
Blenko Glass Company began producing flat glass in 1922, but did not produce glassware until 1930. The company was founded by William John Blenko, who learned glassmaking in England. Blenko was a chemist who could produce hundreds of colors of glass, and he used his skills to produce antique flat glass that was used to make stained glass windows. During the 1920s, his glass company was named Eureka Art Glass Company, and it manufactured flat glass in Milton, West Virginia.
