What gas is used for glass blowing?

oxygen gas
Oxygen is the only fuel source that will ensure the flame is hot enough to effectively and strategically melt quartz and borosilicate glass. In most situations, the glassblower will use oxygen gas at a range of 10-15 psi, with a purity of 95%.

Is lampwork a glassblowing?

Lampworking 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. Lampworking differs from glassblowing in that glassblowing uses a furnace as the primary heat source, although torches are also used.
