Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
In 1940, the U.S. Justice Department filed suit against USG and six other wallboard manufacturers, charging them with price fixing under §§ 1 and 2 of the Sherman Act.

[16] Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
The expected minimum sensitivity of the water-based bare geomembrane liner integrity methods is a one millimeter diameter circular leak. For the arc testing method, water is not required. A high voltage (Approximately 5000V-35000V) with a very low current is introduced above the geomembrane and grounded to the conductive layer below it.
