Calcium Sulfate Terra Alba 1.0

CALCIUM SULFATE TERRA ALBA 1.0 INFORMATION

This Calcium Sulfate is made by grinding and air separating high purity white gypsum that contains about 20% moisture. Depending upon pressure, humidity, loading, etc., this moisture (often called “combined water”) begins to be released when heated above 50 °C. At 180 °C, about three-fourths of the combined water is released. Water is not totally removed until temperatures exceed 400 °C.
