    “Gypsum is an evaporite, which means its crystals form during the evaporation of water,” the San Diego Natural History Museum tells us. Gypsum forms whenever evaporation crystallizes the necessary minerals. In the case of "desert roses" gypsum crystals found around the world in arid sites, formation occurs with evaporation as the level of the water table changes. Gypsum can also be formed ...

    The easiest way to evaporate a sample is to simply heat the sample to boiling. The higher the temperature of the sample, the greater the kinetic energy of the molecules at its surface and therefore the faster the rate of evaporation. Unfortunately, many samples are heat sensitive and the simple addition of heat is not possible as the heat denatures the sample or reduces analyte recovery rates ...

In dry regions it may also be found on the surface, sometimes in the form of gypsum ...

  • Gypsum - an overview ScienceDirect Topics

    When gypsum board is exposed to heat or fire, the water is vaporized, retarding heat transfer. Gypsum also equilibrates humidity and heat peaks. Gypsum board is capable of storing humidity when a room is humid and automatically releasing humidity if the indoor air is too dry. It acts as a thermal insulator because of its low thermal conductivity. Furthermore, it also has ‘heat-storing ...
