  1. I recently pulled out my first mugs from a cone 6 firing. I used Draycott Stoneware from Potclays, UK and fire in oxidation to 1050 degrees c slow bisque and 1222 in a glaze firing, slow cooling to achieve matte surfaces with my glazes.

With two placed next to each other, would the water absorb through and clash with the water being absorbed from its neighbour? Any help would be great! Cheers.
