A kind of pottery, covered with an enamel or white glazing, which gives it the appearance of porcelain. They are composed of a fatty clay, with which is ground a portion of sand, that it may not crack or shrink too much in baking. Vessels formed of this earth require to be dried very gently, to avoid cracking; they are then slightly baked in a furnace, to give them a degree of hardness; after which, the enamel, ground very fine and diluted with water, is applied, and as the ware is very porous from being but slightly baked, it readily absorbs the water, leaving a coating of enamel adhering to the surface. The ware, when thoroughly dried, is then enclosed in cases of baked earth, and subjected to a heat sufficient to fuse the enamel uniformly, and at the same time to complete the baking. Delft ware was formerly made chiefly at Delft, in Holland, from which town it takes its name.
