A Dancik Tip
||"I use polymer clay to make very large (2-4) dapping dies which I then use in the making of hollow plastic beads."|
To make the die I start with a light bulb or a ball or anything with the curve I want in the final bead. I condition a big hunk of polymer clay, powder the top and then press the light bulb into the clay to form the curved depression that will serve as the die. The die gets baked accordingly and then its ready to be used to form the bead halves.
To make a hollow bead, I cut a large circle (as large as the die, if desired) out of 1/16 Faux Bone, Plexiglas, or other applicable plastic and pop it in the toaster oven at about 265 degrees or so and wait until it gets softened not long for such thin material. I remove it from the oven, place the softened plastic circle in the polymer clay die and dap it with the light bulb. It takes just a wee bit of pressure to form the bead, so there should be little chance of breaking the bulb. The plastic hardens in about 10 seconds and can be removed and the other half dapped. All that is then required is the regular sanding of the edges and such to ready them for fusing together.
