of Paris is easy to spread and level. It is fire resistant highly. It forms a thick surface to resist normal knocks after drying . It expands very slightly on the setting. It does not cause cracking of surfaces. It gives a decorative interior finish. It mixes up easily with water.

It is a white powder. When mixed with water (1/3 of its mass), it evolves heat and quickly sets to a hard porous mass within 5 to 15 minutes. During setting, a slight expansion (about 1%) in volume occurs so that it fills the mould completely and takes a sharp impression.
