Bedpan, circa 1900

When enamel-coated ironware was introduced in 1874, manufacturers marketed its durability and handsome mottled gray surface--the origin of its common name, "graniteware." Graniteware was also more lightweight than cast iron and would not rust or corrode, like tinware. Consumers could choose from a wide range of graniteware products, including cookware and other household items, like this bedpan.
