I didn't. Was busy working some glass, and building an oxypropane torch (a blowtorch, hacked to an oxygen feed, powered by normal butane/propane mix torch canisters, but glass tubes connected to the air intake, and to a bottle containing potassium permanganate, plus a second hose, through which a tube goes, connected to a hose length, into which a 150ml glass syringe is fed, containing hydrogen peroxide.
Works by lighting the torch, then feeding in peroxide, which decomposes to water vapor and oxygen plus potassium-manganese salts. The O2 is then fed into the air intake of the torch, making it easy as piss to just inject peroxide when the torch is lit, and have a jet of oxy-propane flame come out. Burns normally with the fuel canisters I use at 1600'C, this modification not sure, but it will cut through borosilicate glass or turn it into a blob.
