Lewis's pottery is made from a gray claybody and formed by hand using coils. After the pot is shaped and dried, a white slip is applied. Without the slip the mineral paints would run off the pot. Next the design is applied using mineral paints and a brush made from the brush holds more paint and makes finer lines than regular brushes bought at a store. Finally on a day when the weather is right for a firing, a small number of finished pieces are carefully pit-fired. Results are rarely 100%. Some pieces will end up cracked, the background on others will be gray rather than white (these will need to be refired), but a few will be wonderful. After going through this process one learns why these pieces should be well taken care of and carefully preserved.
