My ex-husband and myself used to own a business glass blowing and flameworking. It's a lot of fun and I still do it as a hobby! Yes, you do really need to own a kiln. You need it to anneal. Now, is he interested in "glass blowing" where you actually blow into a tube to create a hollow sculpture or, is he referring to flameworking, where you use glass rods and stringers to create the soild sculpture? People tend to confuse the two. If he's interested in glass blowing, do a google search for glass blowing lessons in your area. This is not a hobby that I would recommend as a "teach yourself" thing. Flameworking is a different story. He can easily teach himself to flamework or do lampwork. In fact, you can pick up a basic kit from Hobby Lobby for $100. It is actually a "glass bead making kit" but, it has all the same materials in it that would be needed for other projects. Personally, I would have him start with that kit. It will teach him that nature of the medium and basic technique. I would also have him make a few beads. Beads are basic and he will feel instant gratification from it. Plus, you won't need a kiln right away. He can anneal the bead in the flame. The kit uses MAPP gas, which can be bought at any hardware store. You will also need to buy a pair of UV goggles for eye protection. Well, that's really all I can think of off hand. If you have anymore questions, feel free to ask.
