Top: Plainsman M390 and M350 at cone 6. Bottom: Plainsman L215 and L210 at cone 2. While the latter are still mainly used at cone 06-04 (with commercial bottled glazes), since they no longer contain talc both tolerate higher temperatures much better, by cone 2 they are stonewares. Notice the L215 produces a better red than M390 and L210 a better leather-tan than M350. The first runs of these two were done during March 2022, their code numbers start with the digits shown on these bars: 6983 and 6984. If you would like to experiment with cone 2 stoneware consider starting with our transparent G1916V base glaze and L3685Z8 engobe base. The glaze is expansion-adjustable to deal with crazing or shivering and the engobe is adjustable for firing shrinkage.
