Made a few tube in tubes today at Urbanglass. The outer tube heats the inner and then they both bend. Its tricky, and I am still practicing for sure. Borosilicate is a very different glass and the gas oxy carlisle torches are pretty different- but so nice and hot! I gotta try larger diameter inner and outer tubes next time.
Excited to dust coat some of these, and make a few more!

I had such a blast taking a #scientific glass class with Sally Prasch at Urbanglass. I learned to make ring seals with condensors, and how to bend a tube within a tube- fun but tricky stuff! I made a maraca, trombone/clarinet instrument that I still need to put a bell on. It would be fun to make a bigger, bass maraca-Tromlinet. Yes, the tube in tube stuff does have some neat neon and plasma possibilities too.
