Linoleum is a floor covering made from materials such as solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, most commonly on a hessian or canvas backing. Pigments are often added to the materials to create the desired color finish. Due to the pigment being mixed directly into the linoleum cement, the finished color of the tile remains visible even after years of wear. In the past some of these pigments were iron oxide, red lead or lithopone.
It gained popularity as a beautiful and easy to clean flooring option in the late 19th century and is still used today. Commercially, the material has been largely replaced by sheet vinyl flooring, a plastic alternative made of polyvinyl-chloride, though many still call it linoleum. This is mainly due to the fact that its plastic counterpart is less costly and much faster to produce.
