Blew 400 pounds of sand through our reclaim system last Tuesday and the filter bag still smells like burnt shellac

I was running a heavy brass pour and the old-timer said we needed to keep the mold temp up, so I cranked the torch way higher than usual, and now the whole shop smells like we melted a circuit board, has anyone else had their reclaim system hold onto weird smells after a hot pour?

Burnt shellac smell usually means you got some zinc or other low-temp crap burning off in the reclaim. Try running a cycle with just clean silica sand and a little bit of borax through it, that should help clear the odor. Might take a couple passes.

Oh absolutely, @abby_robinson58 nailed it. I had the exact same issue and that silica trick cleared it right up.
