By far the largest part of the gypsum used in this country goes into wallboard and lath for our homes. These gypsum "boards" are formed by sandwiching a core of wet plaster between two sheets of heavy paper. When the core sets and dries out, the sandwich becomes a strong, rigid, fireproof building material.
Lime plaster was a common building material for wall surfaces in a process known as lath and plaster, whereby a series of wooden strips on a studwork frame was covered with a semi-dry plaster that hardened into a surface.
