A group of nine post medieval cupels used for the refining of gold 16th-18th century. All of the cupels are complete, though of different sizes. One of them has broken into three pieces during deposition but the other eight are all undamaged. They have all been used and there is some grey lead oxide staining in the bowls as evidence of this. Most of the bowls show damage around the rim and base, and all are formed of truncated cones or domed clay with a concave depression upon one side. Cupels are used in refining or assaying precious metals. Bayley, Dungwood & Paynter (2006: 19) w…
