I crafted this bowl using white stoneware clay and shape it on the potter s wheel. It has round edges high enough for serving any dish. Bottom is trimmed so it is stable on any surface. Bowl is glazed with white speckled and gray glossy glaze Please note each piece is handmade so slight variation in coloration and size may occur. I used food-safe glazes and all my work is dishwasher safe, although I recommend hand washing.
