How is Pottery Made? – A Basic Guide

Raw un­processed clay con­sists of clay par­ti­cles and un­de­com­posed feldspar, usu­ally com­bined with quartz, mica, iron-ox­ides and other ma­te­ri­als. How­ever, apart from the coars­est earth­en­ware, which can be pro­duced from clay as found in the ground, most pot­tery is made from spe­cial clays mixed with other ma­te­ri­als or in­gre­di­ents to pro­duce the de­sired re­sults. The mix­ture is known as the clay body.

Shap­ing

The un­fired clay body (green­ware) can be formed or shaped in many dif­fer­ent ways: man­u­ally, us­ing a pot­ter”s wheel or other me­chan­i­cal means (eg. jol­ly­ing or jig­ging), or by us­ing var­i­ous types of molds, or ”for­m­ers” (con­sumed dur­ing fir­ing) to hold the re­quired shape. Once the body is shaped it is usu­ally dried be­fore fir­ing, al­though some ce­ramic artists have de­vel­oped “wet-fired” processes.

Fir­ing

Af­ter dry­ing, the clay body is fired (baked) in an oven called a kiln. Over the years, pot­ters have re­sorted to var­i­ous types of kiln, rang­ing from holes in the ground topped by a fire, to coal or wood fired ovens. Mod­ern day pot­ters typ­i­cally used elec­tric or gas-fired kilns. Continue reading ...
