Oak box with brass key hole plate
Box, oak with brass key hole plate, 20” x 7” x 3½”,[containing: 175 of a set of 200 crystal models showing the Basic mineralogical shapes as described by Carl Immanuel Löscher in the mid 1790s, and illustrated in a developed form in his publication “Beschreibungen Kristallisationen” of 1801” (see note)]
This item is part of the contents of the workshop that Scottish engineer James Watt developed at his home, Heathfield, at Handsworth, Birmingham, from c.1795 through to his death in 1819. Although Watt is best known for his work on the steam engine, his workshop contains a wide variety of objects from many different projects, from chemistry to sculpture-copying.
The description of the item was written by Edward Collins, the land agent responsible for Heathfield when the workshop was given to the Science Museum in 1924. Collins could not always identify what he was looking at, but always described what he saw clearly. This has allowed his descriptions to form the basis of subsequent research.
