Other companies followed his lead- mottled soaps were widely made, by companies such as Christopher Price of Bristol. It is unclear whether they copied Gossage's ideas, or had some kind of licensing agreement. Some sources say that the Gossage company was responsible for 50% of all the UK's soap exports in the 1860s and 1870s.
Though smaller and larger sizes are available, from 15 g (0.53 oz) "guest soap" up to a 10 kg (22 lb) self-slicing block.
