I've described this video to others before. It's a blast from my glassworking past, the film shown to us all as, first and foremost, an example of what NOT to do in a glass shop. We giggled at the pipes flying through the air, exclaimed over the lack of protective eyewear, and were overwhelmed, in the end, by the poverty that hung over each and every shop visited in Firozabad.
I can't believe it's on YouTube now.
The two things that distinguish most studio glass shops in modern first world countries from the times when the Romans began to gather hot glass on the ends of metal pipes and blow it into various shapes, I was told, are the usage of compressed air to cool specific areas of a glass bubble and the usage of propane torches to heat specific areas of a glass bubble. All the rest is more or less unchanged.
Watch Glass India, though, and the third world seems to be still fully encased in the amber of Roman times.
