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.
Crystalline silica was banned for most blast-cleaning operations in Great Britain in 1950 (Factories Act of 1949) and in other European countries in 1966. In 1974, NIOSH recommended that silica sand be prohibited for use as an abrasive blasting material and that less hazardous materials be substituted for silica sand during abrasive blasting.

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
