Sodium aluminum fluoride is called cyrolite by potters and is in a finely powdered (mostly respirable size) form in most glaze mixing rooms, sometimes in over 50 pound quantities or in open bins. It is also an EPA-registered agricultural pesticide, so I'm often surprised at how casually it is used by potters. There are other fluoride-containing powdered materials, but this is the one I worry about most.
