Frost Fern Necklace Polymer Clay and Moonglow Bead Necklace by UnaOdd. Simple, charming fern fronds are impressed into pearly bronze polymer clay and painted a frosty white. The pendant is sanded and a glowing Moonglow bead is strung in the center.
After the piece cools a specific tension is created in the piece due to different coefficients of expansion of metal and enamel. Plique-a-jour pieces, due to the open back, are more fragile than other kinds of enamels.
