The shape of this piece is unknown in the underglaze black repertoire, but found in the so-called 'brown and pearl' wares. This characteristically small example is a waterdropper in the form of a blowfish. Miniature wares are a hallmark of Sawankhalok, and not found in the more limited Sukhothai repertoire.
