One way to test for gypsum is to perform a scratch test - gypsum is softer than a steel nail, so you can scratch it with a nail. Another method is to use a dilute solution of hydrochloric acid - if gypsum is present, it will react and produce effervescence. Finally, you could also use X-ray diffraction analysis to identify the specific crystal structure of gypsum.

Gypsum is one of the softest of minerals. It is only 1.5 on the scale of hardness and can be cut with a knife. Gypsum's specific gravity is 2.2 and it weighs 135 pounds per square foot. It does not melt under a blowpipe and does not react to Hydrochloric acid. It often accompanies rock salt or halite and frequently contains Sulfur beds and may or may not be transparent.
