The Agateware iHORN utilizes an agateware or graniteware funnel to pour out the sound. The first two big US companies making enamel homewares were founded by migrants from Europe in the 1860s Lalance and Grosjean started as a business importing sheet metal and metal homeware before setting up their Manufacturing Company in New York, with a metal stamping factory in Woodhaven. Their mottled enamel was agateware, typically blue. Frederick and William Niedringhaus built up the St. Louis Stamping Co. in Missouri, then moved graniteware production to Granite City, Illinois. They later evolved into NESCO, whose grey enamel was sometimes said to flow from "pure melted granite." They got the first US patent for a mottled enamel finish, just a few months before a competing patent by L & G. The best-known brands, especially the granite and agate ware names, held onto a strong position into the 20th century. They sold for higher prices. In 1899 Lalance and Grosjean’s “Agate nickel-steel ware” was much more expensive than Haberman’s “grey mottled enameled ware” L&G's 2 quart lipped saucepan cost 18¢ ; Haberman's was 7¢. Meanwhile, Sears had a set of 17 pieces of "Peerless gray enamel ware" selling for about $2.70. The Agateware iHORN is pure Americana.
