Anotations

Scope note:

A registered trademark for a type of hardboard building material first made in 1924 by William H. Mason. Masonite is a wet process fiberboard composed of fine wood fibers compressed into a dense, rigid sheet with heat. The fibers are held together by the natural binders from the pulp with no additional adhesive. Masonite boards do not bend or warp easily but the sheets are brittle and break under pressure.
