Glazed pottery has been manufactured for centuries and there has been no change in the general process, the
improvements consisting of greater refinement of materials and better proportioning of the various ingredients.
The process has always consisted of two distinct steps. In the first place the vessel was formed on the potter’s wheel from clay and then fired or baked at a high temperature. This unglazed vessel was then dipped in the glaze -- a bath of liquid (not molten) glass and fired again. But this second firing had to be at a lower temperature than the first, generally a difference of 100 degrees or more. It is this double firing, resulting in two distinct parts to every vessel so manufactured, that accounts for the crazing, checking and cracking from heat and age of ordinary pottery. At the beginning of the present century the late Robert Hall set out to overcome these difficulties, and to manufacture a real baking china, worthy of the name and fit for the purpose -- non-absorbent, heat-resisting, and proof against crazing and checking of the glaze. His experiments, over a long period, led in two directions -- the perfection of a formula which would permit handling of the vessels before they were fired, and a glaze which would permit the high temperature necessary for the vitrification of the body of the vessel. The result is Hall’s Fire-proof China, fired by a single process, body and glaze together, at a temperature of 2400 degrees Fahr. After several years of successful use and remarkable popularity in the best hotels of the country, The Hall China Company began the manufacture of decorated teapots. The unusual qualities of Hall China make it the ideal ware
for teapots. Continuous national advertising has persuaded the American woman that “Bigger Tea in a Hall Pot”
is not only a slogan but a fact.
