The basement of the building that now houses the History of Science Museum was originally Oxford’s first scientific laboratory, which was used to teach students the science of chemistry (and also medicine). Examples of original chemical apparatus from the 17th century are still on display in the Basement Gallery. We also have chemical apparatus demonstrating the development of chemistry up to the 20th century. Highlights include a ‘radium kit’ for home chemical demonstrations in the early 20th century – before such radioactive substances were found to be hazardous.
