MarverA marver is a tool used in glassblowing. It generally is made of a polished steel, brass, or graphite surface attached to a metal or wooden table. For fine applications such as lampworking, a smaller hand-held implement may instead be used. As a tool, marvers date back to glassblowing techniques of the Roman Empire and were made of marble. Warm glass is rolled on the marver, both to shape it and as a means of temperature control.
Borosilicate glassBorosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. The glass has numerous advantages over regular soda–lime glass, including being harder to break when dropped, more resistant to cracking from significant changes in temperature, and having a higher clarity (transparency), which is maintained over a longer period of time. Borosilicate is generally slightly more expensive than soda–lime glass.
Portland VaseThe Portland Vase is a Romancameo glass vase, which dates between AD 1 and AD 25, though low BC dates have some scholarly support. It is the best known piece of Roman cameo glass and has served as an inspiration to many glass and porcelain makers from about the beginning of the 18th century onwards. It was first recorded in Rome in 1600–1601, and since 1810 has been in the British Museum in London.
Blowpipe (tool)A blowpipe is one of several tools used to direct streams of gases into any of several working media.
LampworkingLampworking is a type of glasswork in which a torch or lamp is used to melt the glass. Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. It is also known as flameworking or torchworking, as the modern practice no longer uses oil-fueled lamps.

GlassTransparent non-crystalline solid materialA glass building facadeGlass is an amorphous (non-crystalline) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a "glass" for drinking, "glasses" for vision correction, and a "magnifying glass".
Flux (metallurgy)In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. They are named for the ability to make molten metals easier to flow during smelting. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.
Toledo Museum of ArtThe Toledo Museum of Art is an internationally known art museum located in the Old West End neighborhood of Toledo, Ohio. It houses a collection of more than 30,000 objects. With 45 galleries, it covers 280,000 square feet (26,000 m2) and is currently in the midst of a massive multiyear expansion plan to its 40-acre (16 ha) campus.
NatronNatron is a naturally occurring mixture of sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments.
MuranoMurano is a series of islands linked by bridges in the Venetian Lagoon, northern Italy. It lies about 1.5 km (1 mi) north of Venice and measures about 1.5 km (1 mi) across with a population of just over 5,000 (2004 figures). It is famous for its glass making. It was once an independent comune, but is now a frazione of the comune of Venice.
Bubble (physics)A bubble is a of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop. Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.*As an Amazon Associate I earn from qualifying purchases.
