A stage in the manufacture of a Bristol blue glass ship's decanter.The blowpipe is being held in the glassblower's left hand. The glass is glowing yellow. As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by ...

Lehr (glassmaking) In the manufacture of float glass, a lehr oven is a long kiln with an end-to-end temperature gradient, which is used for annealing newly made glass objects that are transported through the temperature gradient either on rollers or on a conveyor belt. The annealing renders glass into a stronger material with fewer internal ...
A bowl made from cast-glass. The two halves are joined together by the weld seam, running down the middle. Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the 15th century BCE in both Ancient Egypt and Mesopotamia.
A glass melting furnace is designed to melt raw materials into glass. [1] Depending on the intended use, there are various designs of glass melting furnaces available. [2][3][4] They use different power sources. These sources are mainly fossil fueled or by fully electric power. A combination of both energy sources is also realized.
RuneScape. RuneScape is a fantasy massively multiplayer online role-playing game (MMORPG) developed and published by Jagex, released in January 2001. RuneScape was originally a browser game built with the Java programming language; it was largely replaced by a standalone C++ client in 2016.
Gottfried Wilhelm Leibniz or Leibnitz [a] (1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is disputed with Sir Isaac Newton to have invented calculus in addition to many other branches of mathematics, such as binary arithmetic, and statistics.
A very important advance in glass manufacture was the technique of adding lead oxide to the molten glass; this improved the appearance of the glass and made it easier to melt using sea-coal as a furnace fuel. This technique also increased the "working period" of the glass, making it easier to manipulate.
