Faience tablet (H2001-5082/2920-02) made from two colors of faience was found eroding from the Trench 54 South workshop area.
Faience related objects, finds and related materials from ancient Indus sites.
Large lumps of a bluish grey paste that may have been used to make faience objects. Faience is made by melting quartz rock and then regrinding the glassy frit to make a paste that is then fired once again.
Fully and partially glazed faience tablets and other fired objects could be examined after the fire had cooled and the canister opened. The steatite molds were also included in the canister to see how they would be affected by this type of firing.
In order to glaze faience it must be fired at approximately 940 degrees Celsius for several hours. The red color of the glowing faience barely visible inside the canister indicates that this temperature has been reached.
Broken canisters, often with glassy vitrified surfaces, were found throughout the Trench 54 South workshop debris. Lumps of frothy faience slag with embedded fragments of bone were also quite common in the debris.
A concave grindstone and angular pestle found in a room adjacent to the Trench 54 South workshop may have been used for grinding faience paste.
This uniquely shaped tablet (H2001-5090/2913-09), also made with two colors of faience, has an inscription similar to that seen on the pervious slide (247). This tablet was found inside the workshop in Trench 54 South.
