Which common household material is primarily made of mineral gypsum?

A. Drywall
B. Brick
C. Floor Tile

Answer: A Drywall

Ancient civilizations, like the Egyptian, Greek and Roman, used plaster for architecture and decorative sculpture. Centuries later, tradesmen layered plaster over lathing material to form very hard, smooth, durable walls. In 1916, a new product was introduced, and by 1950, it would replace plaster as the industry standard. Invented by U.S. Gypsum, it was called drywall. Unlike the time-consuming, pricey methods used to apply plaster, drywall was faster to work with and also less expensive.

Drywall is a panel of gypsum plaster pressed between two thick sheets of paper. It’s also called gypsum board, wallboard or plasterboard and is used to create interior walls and ceilings. Today, drywall comes in many varieties and has a number of uses. Some panels are fire retardant. Others are made to resist mold growth or to hold up under moist conditions. One thing’s for sure: Drywall continues to evolve and will likely be around for years to come.
