The Museum

Explore the development of the Chemical Industry from ancient times up to the 1940s with reconstructed scenes, archive films and computer quizzes bringing the past to life.

Beginning with early civilisation, the exhibition looks at the use of natural pigments, dyes and new technology concerning the use of materials. It considers the importance of the industrial revolution, the introduction of health and safety laws and looks at some of the great discoveries of the past and the birth of the multi million pound empires of the major chemical companies in the 1930s and 1940s.
