Borosilicate is referred to as "hard glass in that it is similar to Pyrex" and has a higher melting point (approximately 3,000 °F / 1648 °C) than "soft glass", which is preferred for glassblowing by beadmakers.

Lampworking is a type of glasswork where a torch is primarily 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.
