Oh, I'll definitely be reporting back! I just gotta figure out when I can use that Groupon, haha. It expires in mid-December, so yeah... x_x

Just a note that I will be going to my glassblowing class this coming Monday. If anyone has specific questions they think might be helpful to ask my instructor, let me know!

So the class was relatively fast-paced and I was way too distracted by Really Hot Australian Instructor to get a lot of detailed questions in <_< but some things I found interesting include:

- Molten glass at the studio is stored in a furnace heated to 2,100 °F at all times. This furnace was relatively large, I think, and held several gallons of molten glass, and it would apparently take the glass TWO WEEKS to fully cool if the furnace were turned off. It would, similarly, take the furnace TWO WEEKS to heat back up and melt all the glass again. It's doubtful that Luperci would want/need to store molten glass and would just melt/work glass as-needed, but yeahhh.

- In general, I don't think furnaces are very portable, and each furnace definitely has its quirks and works differently from others. As such, it stands that glassworkers wouldn't be able to cart their favorite furnace around in their travels, so glassworkers are probably unlikely to be very nomadic. Since glassware would be more usable in a more civilized Luperci society, there's little incentive for talented glassworkers to leave Russia/Europe.

- Glass cools really, really fast, and cooling too fast can damage it. We reheated our glass constantly in the class as we worked with it, sticking it back in the furnace and rotating it around a while to get it liquidy enough to work with again. Even when the glass piece was done, we stuck it in a "cooling oven" thingy that was heated to ~1000 °F which is "a good temperature for glass to cool at" so that the glass could set without cracking, etc. Conclusion: Luperci glassworkers probably need multiple furnaces to work with and a way to gauge temperatures.

- Molten glass can be "shaped" with wooden instruments soaked in water? This was really weird to me because WHY DOESN'T IT CATCH FIRE idkk??? Our instructor was totally shaping our blobs into better spheres with a rolled up (and very charred) newspaper soaked in water. There was also a wooden spoon-like thing he used. What the fuck even. It smoked a bit, but no fire.

- We were making glass ball ornaments, basically. The molten glass was stuck on one end of a hollow stick thing, which we blew into. It was basically like blowing a balloon, except the stick had to be constantly rotating so the glass didn't drip off. This makes it a two-person job because you really can't rotate a 1.5 meter stick (and the stick is this long so you can stick it into the furnace without standing that close) with molten glass on the end while blowing into the other end. The glass had to be reheated 2-3 times during the blowing process to keep it malleable enough.

- It's totally unavoidable to drip molten glass here and there when you work. There were drip buckets all over the shop filled with shards of glass that cooled after they dripped in, but even so, there were glass shards all over the shop floor. Since Luperci don't/can't really wear human-style shoes, getting feet pads cut up in the a glass shop would probably be an issue.

- The furnaces at the shop were lined with ceramic tiles and then wrapped in "metal." The ceramic holds the heat well and doesn't break, I guess.
