These wonderful PMC pieces are by Melanie Guerra and they are for sale in the Guild
PMC (precious metal clay) is pure silver ground to a fine powder & mixed w/ an organic clay material. This creates a substance to work with that is similar to potters clay, which can be cut, sculpted, carved, stamped & manipulated into any shape, texture, etc...
It is then fired in a kiln & the clay material burns off, leaving just the .999 fine silver, in the shape created before firing! (fine silver is a slightly more pure silver than sterling, .925). Then there are many polishing, stone setting & finishing techniques, and the pieces can stand on their own or be incorporated into beadwork, etc. It is a blend of pottery, sculpture & silver smithing
Melanie Guerra is giving a class on PMC this month. Information here
Melanie will also be at Dedham Open Studios coming up on May 20th.
