The awesome youtube channel Applied Science put out an excellent 40 minute intro video to melting your own glass a week or two ago, going into the equipment, chemistry and recipies: https://www.youtube.com/watch?v=mUcUy7SqdS0 In particular, he talks about making your own photochromic glass that changes color in response to light.

I'd highly recommend his channel to anyone interested in science and fabrication.
