This is a vintage grey stoneware with a blue sponge or sponged design butter pat, butter chip or small butter dish. The blue and grey or light brown butter pat measures 3.25 inches square with a sponged all over pattern. The butter pat or butter dish is in excellent condition with no chips or cracks. There are some slightly under glaze irregularities in the stoneware surface that reflect the light more and frequently occur in hand made stoneware pieces. Butter pats are being used currently as ring dishes, teabag holders and for sushi and sauces.
