John Knight opened his soap factory in Wapping London in 1852, if you look at the other trade in that area you can see how they were all connected.
John moves to Silvertown in 1880 and it became The Royal Primrose soap factory. A lot of the soap was for industrial use and this lot is washing soap , think washboards. One does not want to analyze the content too much ,but enough to say it is a far cry from his well know Knights Castile which had ingredients such as olive oil from Spain.
Yes a lot of soap ! another of my must have items for who knows what !
