cases, though it is likely to have been present. Brass mount no. 935 was coated with silver containing some mercury.

The larger number of analyses from some phases (particularly 9, 11 & 12) is a reflection of the larger number of objects found in deposits attri-buted to these phases. It is elear from these figures that copper and lead/tin alloys were used throughout the period from the late 12th to the early 15th centuries for the manufacture of dress accessories. The smali number of objects in some of the earlier phases make any chronological variations difficult to show conclusively, but there does seem to be a greater proportion of unalloyed copper objects in the 12th and 13th centuries before brass objects became morę common in the 14th century. There seems to be little evidence of any chronological variation in the use of lead/tin alloys with tin and pewter or lead-tin objects found in all phases.
