To make a pyramid out of clay, trim and score a clay block into a pyramid, dry it, apply texturizer, and paint the pyramid. This project days several days. The supplies you need are modeling clay, Styrofoam trays, a knife, a toothpick, modeling paint, texturizer and artist's brushes.
- Trim and score the pyramid
Place a square block of modeling clay on a clean Styrofoam tray. Use a knife to remove the upper corners of the block, and shape it into a four-sided pyramid. Score the sides with a toothpick to create the appearance of stone blocks.
- Dry the clay
Set the tray in a safe place, and let the pyramid dry for several days.
- Apply texturizer and paint
Set the tray on your work surface. Pour equal parts yellow tempera paint and modeling texturizer onto a clean Styrofoam tray, and mix the liquids with a brush. Cover the pyramid in the paint mixture, and let it dry for several hours. Discard the Styrofoam paint tray, and rinse the brush.
- Apply additional texturizer
Examine the painted pyramid to verify that it is dry. Pour a small amount of texturizer onto the Styrofoam tray, and brush it over the pyramid. Let it dry according to the manufacturer's instructions, and then display the pyramid.
