I made a little video on my Rocket Heater Glass Kiln Test, in which we check on one last rocket project from the 2019 Wheaton Labs Appropriate Technology Course, melting broken glass into something more interesting in a Rocket Heater. Here's the idea: Melting bottle glass requires sustained temperatures up to 1600 degrees Fahrenheit with a long slow cool down to strengthen (anneal) it. So where do I find temperatures like that without a massive expenditure of fossil fuels? Try the heart of my Rocket Heater on any cold winter night.
