Just realized my new zircon sand additive is causing way more smoke than expected
I switched to a different brand of zircon sand for facing molds last week, and the pour area got so smoky we had to pause production. I learned the new stuff has a much lower ignition point than my old supplier's blend. Has anyone else run into this and found a good way to manage the fumes without switching back?

Our old zircon never smoked enough to stop a pour.

Actually, a zircon that doesn't smoke much could be a good thing. It might mean the material is cleaner and more stable under heat. You wouldn't want a ton of smoke messing with the clarity or the structure during a pour. Maybe that old one was just efficient.

Right, because the real problem in metal casting is definitely too much clarity. My last zircon put on a smoke show like a cheap magic trick, but at least I knew it was working. If your old one was that clean, maybe it was just taking a nap in the crucible. I'd take a little honest smoke over a silent, lazy grain any day.
