the mechanics of the operation havn't changed in a very very long time.
no computers, no fluff, just medieval like so:
glass is melting in the top one at roughly 2700 degrees Farenheit. standing in front of it feels like you're on fire.
the bottom one is called a "glory hole" and is used for keeping the glass hot.
it's ridiculously hot, but not as bad as the top one.
the tools you use look like this:
Jacks, Tweezers, and snips/shears
they're all big and made of iron.
also you use a long metal pole to keep your glass on.
I took some gathers and sanded the bottoms while i was there
(It was a short class)
it was quite an experience.
I don't like heat in general but it's nice to say that i tried it.
and I have a burn from the end of the jacks to prove it.
