Perkin took out a patent on his accidental discovery on 26 August Excitingly for the museum, a researcher at the University of Aberdeen contacted us in about his research into how mauveine was made. When he compared his results, he found something unexpected.

Sir William Henry Perkin had been keeping something secret. Dr Plater believes that the changes Perkin made are linked to the mass-production of the dye. One change in particular increased the amount of dye that could be synthesised and was a major leap forward in synthetic dye production. We love it when our historical collections are used to further contemporary knowledge about science and technology.

Now, what accidental discovery are you going to make that might change the world? Or what might you find in our collections that will inspire you to make a discovery of your own? I think you should also talk about the risks associated with aniline dyes.

Making Color Making Color. Frank, Sea snails like these are found around the world. When poked milked or crushed, they secrete a substance that was used for making purple dye as early as BC. Thousands of snails were needed to color a single robe, and for centuries purple dye was more valuable than silver and worn only by royalty.

Mixtec weavers in Oaxaca, Mexico, color locally grown cotton with natural dyes — including the rare purple tixinda , extracted from the Plicopurpura pansa mollusk. The introduction of synthetic dyes and the decline of mollusk populations have greatly reduced the production of natural purple dye. When coal was carbonized to make coke a fuel , or gasified to make coal gas, one of its by-products was coal tar.
