The use of frit in this paste lent it the names ""Frittenporzellan"" in Germany and ""frita"" in Spain. In France it was known as ""pâte tendre"" and in England "soft-paste", perhaps because it does not easily retain its shape in the wet state, or because it tends to slump in the kiln under high temperature, or because the body and the glaze can be easily scratched. (Scratching with a file is a crude way of finding out whether a piece is made of soft-paste or not.)
