Description: | Cast copper alloy foot from the leg of a cauldron, triangular in profile, with the base at right angles to the back, and trapezoidal in plan and in section at the base, and semi-circular at its broken end which would have attached to the leg. The front of the foot has two slight ridges in profile, but poorly cast if it was meant to have claw-like features. The following report was made by Fiona Thomas of Camborne School of Mines: Compound % Concentration Al 0.22 Si 0.38 P 0.04 S 1.12 Cl 0.60 K 0.10 Cr 1.06 Fe 5.60 Co 0.31 Ni 1.75 Cu 61.13 Zn 0.13 As 3.23 Sn 2.30 Sb 5.51 Pb 16.30 This was then analysed by Dr. Peter Northover at Oxford Materials who commented: "It is medieval, probably dating from the 14th to the 15th century, but could also date from the first part of the 16th century. It may be an ingot fragment, but commonly fragments from tripod cauldrons, like their feet, can be mistaken for ingots. The metal was imported into Britain from the continent: a) because England was not producing copper at that time, and b) because no British source could produce that level of antimony. The lead, though, may have been added by whoever cast the object in Britain." The porous and pitted surface on the base of the foot suggests that some of the elements within the copper alloy, such as the lead, antimony and tin, may have been leaching out over time while the foot lay in acidic soil. Read (1988) illustrates a similar example on page 95, No.600, which is dated from the 13th to the 17th century. Butler and Green (2003) illustrate a cauldron with everted feet on page 166, Fig.1, which is dated from the 15th to the 16th century. Egan (1998) illustrates a similar example with a solid plano-convex foot at right angles to the leg on page 164, Fig.132, No.457, which is dated to c.1350-1400.
