PMC Flex is a pure silver clay that has been formulated to provide
an extended working time and it does not completely harden at room
temperature. This means it is now possible to make "crack free" coils,
ring shanks, sheet and much more without having to rush! Projects can
even be stored away for several days before finishing and the clay will
still be flexible!
To carve or sand PMC Flex, simply dry the object by heating
to 300ﾟF for about 20 minutes. Firing and finishing is the same as for
all other fine silver PMC clays.
