Pewabic Pottery Arts & Crafts Copper Lustre Tile
A high fired red brick clay tile with an impressed circular design. The recesses filled with a bubbling volcanic copper lustre glaze. Unmarked, attributed to Pewabic Pottery, found in Michigan. It measures about 6 1/4" square. The dense and heavy red clay slab is slightly cupped and has a shallow chip on the back edge. Traces of mortar remain.
Beautiful when the sun reflects on the copper glaze.
