Basics of thixotropy :: Anton Paar Wiki
Examples of thixotropic materials are lotions, gels, ketchup, paints, and gypsum. For example, ketchup flows out of the tube when it is pressed. Its viscosity becomes lower as force is applied. After the force lessens, the viscosity of the ketchup recovers to its initial state for perfect leveling on French fries.

Gypsum – Electro Magnetic Industries
Gypsum. Natural gypsum (CaSO4 • 2H2O), also known as gypsum, could be processed into βhemihydrate gypsum (CaSO4 • 1 / 2H2O) by calcining and grinding, namely building gypsum, plaster or stucco. If the calcination temperature is 190 ° C, we can obtain model gypsum, whose fineness and whiteness is higher than construction gypsum.
