Food for thought... wet aluminmum into molten aluminum can cause an explosion. Do not push cans through the top hole... it will exellerate destruction of kayowool. Shred the cans before hand for better reclaim %. Overall good video. But be careful, cause you already walking that line hard.
@thetoolguy82 Not sure . All I know is that a kiln is required to harden the glaze , there aren't any videos on doing it , though . If you did decide to do it , I think you'd be the first .
Pottery glazes work by melting at different temps to turn to glass, the hardening happens when you cool the molten glass. Don't think this is what you'd be after here. @@Airon79
