I read recently (this morning looking for it) that the temperature required to turn sand into glass is 1700C or 3090F
It would be very educational to today's kids to try to do this for a life lesson. Since Iran is not being very friendly, how about starting with all the sand areas in the country? The magical sight of ordinary desert sand (dotted with the odd camel poop here and there) magically turning into shimmering sheets of glass - reflecting the sun and the moon at night - serve as a great model to kids. And it's scientific! Desert sand is varied thus the results will be, too. Areas of glass could act as stepping stones on the sand!
No praise, please. It's what I do. Anything for our precious children.
