- Description
- This clear plastic template contains five circles, a rectangle, a square, a parallelogram, and two triangles, along with thirteen pieces of chemical apparatus.
- By the 1920s, students studying chemistry in American colleges and universities were expected to keep detailed laboratory notebooks. To help them in this endeavor, laboratory apparatus firms such as Eimer and Amend in New York, as well as CENCO, E.H. Sargent & Co., and W.H. Welch Company (all of Chicago) sold stencils with cutouts in the shape of chemical apparatus. All of these firms sold a stencil that shows the chemical apparatus on this object and the five circles. These stencils were cut off on one side (hence in the shape of trapezoids and not a rectangle) to assist in drawing bent delivery tubes. This eliminated the triangles, square, parallelogram, and rectangle on this instrument.
- A template precisely like this one is found in a 1967 catalog of the C-Thru Ruler Company of Bloomfield, Connecticut. Called a “chemistry and math stencil,” it sold for $1.80 a dozen. That catalog also contains a “chemistry stencil” like – but not identical to – those found in the earlier catalogs of chemical supply companies.
- The donor presented this object along with a set of drawing instruments by Dietzgen, although the template is not by Dietzgen. The gift was given in memory of his father, Edward Bradley Morrison, and in honor of his son, Joshua Bradley Morrison. The donor had been told that his uncle got the set from a friend who assisted with the restoration of the U.S.S. Constitution; the uncle then gave the set to the donor's father for use in his college studies.
