During the Victorian Era, the toxic compound copper acetoarsenite was frequently used to create a bright green binding color. Inspired by the Winterthur Poison Books project, this exhibit examines the context and history behind copper acetoarsenite and the field of chemistry during this period, as well as the rise of workplace safety regulations. It explores the available testing methods for identifying this toxic compound and gives practical tips and advice for safe handling of books and materials.

This exhibit is free and open to the public. Learn more about visiting Stanford Libraries on our website.
