Note 5 — Chapter IV · Economic Life Production (continued 2)

The Government analyst5 who analyzed the clays and examined the finished and glazed pots says of the Samoki pot that about two-thirds of the organic matter in the clay is consumed in the baking or burning of the pot. The organic matter in the middle one-third of the wall of the pot is not consumed. The clay is a remarkably hard one and is difficult of ignition; this is the reason it makes good cooking vessels. He further says that the glaze is not a true glaze. It seems that the resin does nothing except lose its oils when applied to the red-hot pots, and there is left on the surface the unconsumed carbon.
