Enameled metal tools, kitchen utensils, jewelry and enameled boxes have a history confused by the several meanings of the word “enamel.” The first enamel on cast iron was made in Czechoslovakia about 1830, and used to make kitchen utensils, but it was discovered that it created lead that contaminated the food. They soon improved the process. Next came sheet metal pots in 1859 in Germany. Enameled cooking pots were not made in the United States until 1867 by John Kohler whose name is still prominent in the industry. Then came American stoves in 1890, followed by refrigerators, bathtubs and wall tiles. By 1900, Boston artists used enamel on artistic ritual church pieces, jewelry, and attractive boxes made of silver, gold and precious stones in the Arts and Crafts style.
