Inspect foundry equipment on a frequent basis for cracks and signs of wear. Never introduce water to the furnace or crucible. A trace amount of water can cause a large explosion. Pour and melt in areas that have a nonflammable surface such as metal or sand. The molten metal that is spilled can travel a great distance, so keep the work area clear.

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.
