Historical information
From the 1860's - 1930's various companies called their enamelware products by their own unique names, e.g. graniteware and agateware. The enamel coating put an end to metallic tasting food and prevented rust from contaminating food. It did scratch and chip easily. This large mug could have been used for storing dripping or other liquids for cooking.
