This is a reproduction of an argillite frog bowl in the Canadian Museum of Civilization collection. It is 3-3/4 inches in length. Wooden bowls were in common use to hold oil to accompany food and were often elaborately carved. Small grease bowls were often in the shape of frogs. Argillite bowls were made specifically for the trade in scrimshaw work where argillite commanded a much higher price than wood. Color is argillite black. This museum quality reproduction is made from a natural resin composite to attain the heft of the argillite original. Made in Canada.
