These interesting leaf shapes are iron, so they can be enameled, but getting the whole piece hot enough is difficult and the result is a very delicate piece that cracks easily, so I don't recommend it. They can be colored with guilder's paste. They make fun an funky earrings and cool foundations for other beads to be wired on. This listing is for 10 findings 45 x 50 mm. Wonderful for Victorian, steampunk, and boho designs.
