Castolite Company promotional mailers

 Collection
Accession: 2845
Abstract:

The Castolite Company was a retail wholesaler of a clear, liquid plastic (or polyester resin) called "Castolite," which was used for casting, embedding, laminating, molding, or coating. The company was founded in 1948 by William Weers (1906-1976). Initially, the scientific community used Castolite for embedding biological specimens into clear, liquid plastic, among other scientific applications. The process became popular in the arts and crafts community, and hobby shops frequently sold Castolite. This small collection includes 1952 promotional sales materials for Castolite and its uses for making jewelry and other homemade creations; the purchaser could then sell their products for personal profit.
