Field tiles are the workhorses, the solid and softly patterned tiles that surrounded the decorative centerpieces and filled a fireplace, a wainscot, or a floor. Sold here in lots large enough to do real work — a full surround, a backsplash, a bath — in glazes that a century has only deepened. Crackle and mottled glazes, subway runs, marbled and ochre fields; original, period, and priced by the lot.
