Composition Mouldings

The heritage of compo can be traced back as far as the Egyptian. Italian Renaissance craftsmen called the material “pastiglia” and used it to adorn picture frames, chests and caskets (“Utility and Beauty” by Mark Reinberger – University of Delaware Press). By the mid 1700’s the formulation and techniques of compo had spread to the workshops of England and France and from there found their way to North America – brought over by European artisans immigrating to the New World. Some of the best examples of compo ornamentation can be found in the Winterthur Museum and Library – Winterthur, Delaware.
