The support material is smooth and the soft layer material is composed predominantly of a powder-like, asbestos-free mineral base material. The mineral base material may include mostly a chemically and thermally untreated material and also a chemically and thermally or only thermally treated material. A method for making such a sheet or plate is also disclosed.
