Leah Kartovicky : Clay facts Cone firing facts
 * 1) Often a potter does not use one type of clay, but may use a mixture of clays to get the result that she is looking for.
 * 2) Kaolin is very pure, with a white color and it does not shrink very much when fired, and must be fired at a very high temperature
 * 3) Fire clay usually has a very rough texture, and is often added to stoneware.
 * 4) Ball clay has a finer grain than fire clay, and shrinks a great deal during the firing process
 * 5) Earthenware is very common, and generally contains a fair amount of iron
 * 6) Earthenware does not generally need to be fired at very high temperatures.
 * 7) Primary clays have larger grains, and have remained close to their original source.
 * 8) Secondary clays are a sedimentary type of clay that has been carried away from its original source by wind, running water, and other forces.
 * 9) Kaolin must be fired at a very high temperature
 * 10) Kaolin is usually not used alone, as it does not have a high degree of "plasticity," that is, the ability to be malleable and easy to work with.
 * 1) Very low firing is usually used for luster glazes and very low-firing overglazes
 * 2) Low firing has historically been the most commonly used firing range
 * 3) low-fire temperatures allow potters to use a variety of colorants that either burn off or become unstable at higher temperatures
 * 4) lower mid-range is the range where most earthenware and other low-fire clay bodies actually mature to their strongest and most durable state
 * 5) mid range is now more popular because of the availability of electric kilns that can comfortably reach this range without severely decreasing the kiln's and the kiln elements' lifespans.
 * 6) High fire allows glazes and clay bodies are dense and durable
 * 7) <span style="color: #333333; font-family: "Verdana","sans-serif"; font-size: 12px;">High fire the color range is limited, because of the varying effects of oxidation and reduction on glaze colorants, the few coloring oxides that are viable at this range can still produce a rich, if much more limited, palette.
 * 8) <span style="color: #333333; font-family: "Verdana","sans-serif"; font-size: 12px;">Very low-fired overglazes and lusters are then applied to the already fired primary glaze
 * 9) <span style="color: #333333; font-family: "Verdana","sans-serif"; font-size: 12px;">low-fire temperatures allow potters to use a variety of colorants that either burn off or become unstable at higher temperatures.
 * 10) <span style="color: #333333; font-family: "Verdana","sans-serif"; font-size: 12px;">Low-fired ware can present some difficulties, like the clay body may remain overly porous
