San Ildefonso Style Black-on-Black Burnished Pottery Bowl

This is a hand-coiled ceramic bowl featuring the distinctive black-on-black matte and polished finish characteristic of San Ildefonso or Santa Clara Pueblo traditions. The piece shows a globular, rounded form with a slightly inverted rim. The exterior surface is divided into two distinct zones: a highly burnished, mirror-like upper shoulder and a textured lower body. A decorative band encircles the shoulder, featuring incised or carved geometric diamond patterns framed by parallel horizontal lines. The 'black' coloration is achieved through a specific reduction firing process rather than glaze. In terms of condition, the item exhibits significant surface wear including extensive scuffing, micro-scratches, and a dulling of the original high-polish finish, likely from handling or improper storage. The lower section shows a mottled, grayish patina which may indicate mineral deposits or loss of the original carbonized surface. Based on the construction and decorative style, this piece likely dates to the mid-to-late 20th century. While no maker's mark is visible in the provided view, the craftsmanship demonstrates traditional indigenous techniques, though the current surface condition affects its aesthetic value and requires professional conservation to restore its luster.
