Sand, perlite, grog, and vermiculite contain free silica and are, therefore, highly toxic by inhalation. Vermiculite is also frequently contaminated with asbestos. There is a danger of accidents if clay or water can be added while the mixer is in operation. Bags of clay and glaze materials can be very heavy, and lifting can cause back problems.
