Pieces will then dry for about a week before being fired. After it is fired, students will come back to paint it. After a final firing, pieces are ready to be picked up. This is approximately a 2 week process from start to finish. This is a very popular class so call to book your class as soon as possible.Kiln Firing: Transformation Through EvaporationCeramics are some of history’s most enduring objects. Check out Groupons study of how a lump of clay becomes a piece of art to last a lifetime.Though it was once clay, a ceramic pot will never revert back to a moldable state—not even when an archeologist digs it up in 2,000 years hoping it contains fossilized cookies. This permanent transformation is due to the pot’s adolescent incubator, the kiln, whose scalding belly fundamentally alters the molecular make-up of clay as it bakes inside. In its pliable state, clay is composed of silica and alumina molecules lightly bonded by molecules of water. For the transformation to occur, these water molecules have to go, and the heat of a kiln causes the moisture to evaporate. This process must happen slowly, however, lest the water turn to steam and cause the piece to explode. Once the kiln reaches waters boiling temperature (212 degrees Fahrenheit), much of the moisture has left—except for the molecules bonding the clay together, which don’t evaporate until around 572 degrees. At this point, no amount of water splashed onto the clay will wake it up or make it pliable again, but the sauna session isn’t over yet. Further milestones are reached at 1,063 degrees, when the silica oxide molecules rearrange themselves (a process called quartz invers
