Video: Glass Made on a Charcoal Grill (Don’t Try This at Home)
The UberReview —
I have seen a lot of crazy experiments in my time, but this one has to take the cake. Theo Gray over at Pop Sci managed to make himself a glass ornament on a charcoal grill. By adding washing soda, lime or borax to silica beach sand, it is possible to reduce the temperature required to make glass from 3,000-3,500°F to a still toasty and very dangerous 2,000°F. He manages to attain this temperature using a vacuum cleaner and a Weber grill and produces a small glass ornament for his troubles.
He adds the disclaimer, which is worth noting, that pushing a grill beyond its intended temperature range is very ...
PopSci Shows You How To Make Glass On A Grill, Begs You Not To Do It [Science Experiment]

Did you know you could make glass on a regular charcoal grill? Sure it's incredibly flamey and pretty dangerous, but according to the folks at Pop Sci, it's possible! All you need to do is add washing soda, lime or borax to white-silica beach sand and a grill overclocked to reach temperatures of 2000°F. Check out Theodore Gray feeding a concoction of silica and washing room regulars into a cast-iron pot over a flaming grill and getting two pretty medallions out of it. Try to resist doing this at home afterwards. [Popsci]

HOW TO - Making glass with a grill and vacuum cleaner
MAKE Magazine —
Theodore Gray @ PopSci writes -
All the components of glass can be found in two places: the beach and the laundry room. It’s possible to melt pure white-silica beach sand into glass, but only at temperatures of 3,000 to 3,500°F. Washing soda, lime or borax (a traditional laundry aid) added to the sand disrupts the quartz-crystal structure of silica and reduces the required temperature to a more practical, though still dangerous, 2,000°F, which I achieved with a backyard grill and a vacuum cleaner. Glass is thought to have been discovered around 7,000 years ago by ...
