78 rpm materials

Early disc records were made of various materials including hard rubber. From 1897 onwards, earlier materials were largely replaced by a rather brittle formula of 25% shellac, a filler of a cotton compound similar to manila paper, powdered slate, and a small amount of a wax lubricant. The mass production of shellac records began in 1898 in Hanover, Germany, and continued until the end of the 78-rpm format in the late 1950s. “Unbreakable” records, usually of celluloid on a pasteboard base, were made from 1904 onwards, but they suffered from an exceptionally high level of surface noise. “Unbreakable” records could be bent, broken, or otherwise damaged; but not nearly as easily as shellac records. Vinyl was first tried out as a 78 rpm record material in 1940 due to material restrictions. Decca introduced vinyl “Deccalite” 78s after the Second World War, and Victor made some vinyl 78s, but other labels would restrict vinyl production to the newer 33 and 45 formats.
