I stumbled across this video on youtube. It's pretty technical, but utterly fascinating. This dude is talking about making batches of photochromatic boro glass. Melting the chemical and making glass from scratch.
Some of the stuff he talks about is stuff that we've learned from working with glass and come as second nature - other things he talks about are - well - just plain cool. I have never thought of glass as corrosive - but I wouldn't have put the ingredients into a mold, heated it up, and expected it to come out. However - I did not know that glass doesn't stick to platinum. (And I was unlikely to find that out by accident ... ).
I've had to watch it multiple times to get my head around some of it.

What is that flame?
Alrighty then, you know everything there is to know about glass, but what about your most important tool? The flame? Just what IS a flame anyway.
Check out this video, sponsored by the What is a Flame science challenge - sponsored by Alan Alda - that explains what a flame really is, in terms an 11 year-old can understand. \
Of course, for us, it's a little different, different fuel, gas instead of wax, but if nothing else, this should help you get your head around flame chemistry and the difference oxygen makes.
