A cute little porcelain blank, made for Overlay, but could be used for so much more... why not try our decals? You can paint overlay straight onto the porcelain, and embedd the blank into the clay or make your own bezel. They can be fired with your clay!
"Making Silver Overlay Jewellery with Glass and Porcelain" book has some great projects in for these, along with some stunning other pieces. See image two for a sneak preview from this book.
Here you get one round blank, measuring 10mm.
