Water hardness
The hardness of water is caused by the dissolved salts of
calcium and magnesium, principally carbonates, sulfates and
silicates.
Temporary hardness
When the temperature of the water is raised, part of the salts
are precipitated as calcium carbonate and magnesium hydrox-
ide. This is termed temporary or carbonate hardness.
