Glass what?!
Melting solid glass into liquid, and balancing it long enough for it to solidify again – maybe puffing in some air to inflate the bubble – this is lampworking.
When you think of glass blowing, you likely think of grand furnaces with workers dipping steel handles into large vats of molten glass before puffing, shaping, and working the molten glob into a form or vessel. That’s called furnace work, or hot shop – as I’m sure you could guess – the environment is more than warm!
