    Sorry Trish
    Never heard of a shrinkage ruler ~ is it for a specific purpose? (eg. rings)
    A few of the rolling mats that silverclay sell have measurements on
    having said that I've always found shrinkage can be a bit randon depending how long and
    how hot the piece is fired....

    Default PMC shrinkage

    The ruler has the measurements for unfired PMC and the measurements for fired Pmc so you can calculate what size you need to make your piece allowing for shrinkage.
    I know you can get one from Rio-Grande in the USA and mentioned in some metal clay books . but cant seem to trace one in the uk.
    I did see instructions for making one online somewhere but it seemed a bit complicated .
