Bisque Ware

When a pot has completely dried, and before it is glazed and glaze fired, a first firing, called bisque firing, is often done. The resulting pottery is called bisque ware. Bisque firing serves the purpose of giving the pot considerably more strength than is has when it is simply dried clay (greenware) thereby allowing the potter to handle the pot more readily without fear of breaking it. However bisque firing still leaves the pot pourous enough that it can pick up glaze from a suspension of glaze materials in water. While potters bisque fire to somewhat different temperatures (or cones) a typical firing would be from 1700-1800 degrees Fahrenheit. Some potters are able to skip the bisque firing step by either 1) very carefully applying or spraying glaze directly on greenware, 2) not glazing their pottery or 3) applying glaze in the kiln via salt or soda glazing. Given the particular effects I want to achieve at Frog Pond Pottery, bisque firing is necessary to prevent breakage during the glazing steps that I use.
