A domestic clock with a bakelite casing. Bakelite,the first plastic to be used for widespread commercial purposes,was discovered in the 1920s while Belgian chemist Leo Baekeland was researching synthetic varnishes in the USA. It is a thermosetting plastic (one that does not melt once it has been heated and set) and it is a good insulator. This made it the ideal material to use in electrical devices like telephones and radios,and its ease of moulding made it popular as a decorative material for household items | |
