I just finished the beginner glass working class here at HACC. Simply stated its an affordable class that teaches casting, fusing, and blowing. I've found that I am a furnace worker, but fusing glass is just as fun.

They're four years old and Reuben's not the professor anymore, but that's our hotshop. If you want a really good class thats pretty inexpensive, and are in the Harrisburg area, be sure and check us out :)
