Native American pottery is traditionally coiled thickly, then scraped down to as thin as needed. Scraping it with a thin metal rib (Kemper's S4) refines the shape. The pots are then polished by hand using either a soft cloth, smooth rock, or even a stainless steel spoon. Micacious clay is traditionally wood fired outdoors to temperatures of around 1200 F. The interesting colors, caused by smoke and fire, range from red to orange to gray. It is important to remember NOT to fire burnished pots over cone 08 as the shine will fade.
