Whiting, Paris white, or Spanish white is mere prepared chalk. To make ordinary whiting, mix ground chalk with water, and allow the sand contained in the chalk to settle in wooden troughs; then transfer the liquid to other vessels where the whiting itself will fall as the sediment. This is dried by the aid of heat. A similar procedure is followed in making Spanish or Paris white,but the chalk is more thoroughly washed and a better and harder quality of chalk - cliff stone - is used.
