The potential hazards involved in glassblowing should be obvious. But there are various ways of minimizing those hazards - and one of them is by wearing appropriate clothing.
Closed-toe shoes only! Molten glass is soft enough to drip, in which case you don't want your feet under it even in boots!.
Cotton shirt and pants only! Many synthetics melt with the heat, and will become very sticky!
In the "not exactly clothing" department, long hair must be pulled back and tied! We get eyebrow and arm hair singed all the time - think about what long, loose hair could do!
Long pantsare a must - you'll get plenty warm in them, but I can show you a couple ugly calf scars I got from wearing shorts!
Safety Glasses- will be provided, but MUST be worn AT ALL TIMES in the glassblowing area. Still-hot glass can pop off the pipes while cooling (which means "less then 1,000 degrees F) and fly surprising distances!
