Earthenware is glazed or unglazed nonvitreous pottery [2] that has normally been fired below 1,200 °C (2,190 °F). [3] Basic earthenware, often called terracotta , absorbs liquids such as water. However, earthenware can be made impervious to liquids by coating it with a ceramic glaze , and such a process is used for the great majority of ...
The term "biscuit" refers to any type of fired but unglazed pottery in the course of manufacture, but only in porcelain is biscuit or bisque a term for a final product.

Guanajuato produces both glazed and unglazed pottery. In small indigenous communities, brown pieces with black decoration are produced. [2] The city of Guanajuato makes black ceramics with gold decoration, a style introduced by an artisan named Behrens. It is not traditional but his work has been imitated, often not to the same quality. [2]
This can be a final product such as biscuit porcelain or unglazed earthenware (such as terracotta) or, most commonly, an intermediate stage in a glazed final product. Confusingly, "biscuit" may also be used as a term for pottery at a stage in its manufacture where it has not yet been fired or glazed, but has been dried so that it is no longer ...
It typically has a painted design of small, formalized flowers made up of round dot petals painted in white slip on the natural red of the clay, then fired with a clear glaze. The flowers may be limited to a band or applied lavishly over the entire piece. The latter is frequently done with casseroles and flower pots.
Most of their pieces are pots with lids, cantaros, small jugs, miniature figures, water glasses with their own tray, platters, bowls. After forming and drying, the pieces are fired for the first time in wood or gas kilns. Then they are painted using commercial enamel paint mixed with a slip.
Jasperware, or jasper ware, is a type of pottery first developed by Josiah Wedgwood in the 1770s. Usually described as stoneware, [2] it has an unglazed matte "biscuit" finish and is produced in a number of different colours, of which the most common and best known is a pale blue that has become known as "Wedgwood blue".
Raku is a unique form of pottery making; what makes it unique is the range of designs that can be created by simply altering certain variables. These variables—which include wax resist, glazes, slips, temperature, and timing [ 16 ] —ultimately determine the outcome when firing a piece of clay.
