So we had some home-brew rocket propellant to dispose of properly, which requires a burn. An old copper fireplace provided the perfect opportunity to test the melting point of copper at 1984°F. It yielded like butter to a torch, and we may have had a secondary copper-thermite reaction boosting local temperatures to 7000°. I have some very cool slag in the office now, of copper and whiskey bottle glass. This was the finale at our international gathering of investors, after a brilliant blue burn of nano-boron and the sparkling fountain of titanium sponge.
