Varieties of Enameledware

"Agate" ware is one trade name for the mottled ware, so named because it somewhat resembles the mottled appearance of the agate. It is a specially durable variety of enameled ware.

"Granite" ware is another trade name for the gray mottled ware, so called because pulverized granite is actually added to the "batch" and also because its gray mottling somewhat resembles granite.
