Silicon is not only the stuff of microchips. For much longer it’s been the main ingredient in recipes for glass. Appropriate then that one of the Bay Area’s premier glass workshops, the Bay Area Glass Institute, is located in San Jose, silicon central. They offer four day glasses for beginners, even seniors with hardy lungs, who are not intimidated by working around 2000 degree furnaces. If you’re just window shopping stop by and peruse their art glass store. Similar programs are available throughout the Bay Area. Google will find them.
