A history of clay and pottery ... Called a low-fire clay, earthenware fires (or bakes) in a temperature range of 1700 to 2100°F (926–1150°C). After firing, it is still porous and—unless glazed—is often white or gray. Earthenware is commonly used in the making of terra cotta pots, roofing tiles, and other low-fire ware.

How to fire polymer clay ... Firing is the process of heating the clay to make a finished piece. During firing, the temperature causes chemical changes in the clay, making it hard and strong. Polymer clay fires at low temperatures (below 300° Fahrenheit), so you don't need a special kiln - you can fire it in a kitchen oven.

This term refers to bubbles, bulges, swelling or "pimples" protruding from the surface of the clay body after firing, ... Broadly, the cause is firing too fast or too hot. The temperature range of 1150 F to 1900F (approximately cone 020 to cone 06) is critical since that is when most of the volatiles burn away.

There are basically two main temperature ranges in the firing of clay - stoneware, and earthenware. Stoneware is fired hotter (about 2300 degrees) and earthenware is fired to a lower temperature. (About 1925 degrees, give or take.) These differences can be profound to the potter.

Note that the primary difference between the categories is the maximum firing temperature possible. Earthenware clays will MELT if fired to the higher temperatures of stoneware and porcelain. This is extremely important to know when purchasing clay for use.

Low fire clay fires to 1200 F which corresponds to cone 019-020, the highest recommended firing temperature of all silver is 1650F or cone 010-011. Ceramic kilns fire much slower than jewelry kilns so the actual hold time is not too important.
