The core material of drywall involves gypsum. There is no shortage of the raw material; Gypsum is produced in plenty of supply throughout the world, so drywall can be produced in most developed countries with deposits. Gypsum can be up to half water, but due to the properties of rock, the moisture remains in a solid form like ice until the temperature rises to 212 degrees Fahrenheit. This makes a fairly light, solid material that can dampen fire at high temperatures.
