I got a really cool new enameling supply from Thompson Enamel- It's a white overglaze enamel that can be used to paint opaque white details over darker colors. I apply it the same way I apply my black overglaze linework in my other enamel pieces. I thin it out with a little turpentine and draw it on with a crow quill pen. When I fire it it fuses with the base coat to make a permanent drawing in enamel. This pendant is the first item I made with it. I think it's pretty nifty!
