This silly skull egg was made with a fluorescent powder (recommended by Ginger in blue bottle tree) and translucent polymer clay. I kneaded in as much as I thought I could get away with, and the clay felt a little chalky.
Apparently I needed more. It does glow a little in a dark room, but not enough to get a picture on my phone. So here are two sunny views of the three toothed cranium and mandible.. ha ha… all made over an egg.
First basic layer was made (leaving eye and nose and mouth without polymer clay, and after the first curing, i just chipped out the eggshell in those areas, and sanded around and chipped some more. I then added the mandible and ridges over the eyes and zygoma and figured in where the teeth should go, and cured it again. Lastly, I added the three teeth (the hardest part, ha ha), cured again, and painted with black and brown acrylic paint the inside of the head. I thought about using pencil or ink to mark in the cranial sutures and foramina… ha ha. I am not totally sure why this guy looks so smiley for a skull.
