Stone cardboard

Stone cardboard is a kind of paper mache or paper mache, a mass of softened and crushed paper , mixed with glue and water and mixed with clay , chalk , and sometimes with linseed oil . The specialty is the very high proportion of whiting , which makes the material more rigid.

Stone cardboard was used for the production of dolls' heads , as a writing board and as a fireproof building material, for example in the 19th century as roofing material (so-called stone cardboard roofs).
