How do I get a marbled effect? When two colors of clay are thoroughly mixed, the distinction between them disappears. However, if you stop the mixing partway, you'll get a streaked effect similar to marble. (Make sure not to stop mixing in time to preserve the marbled grain you want; continued handling of the clay will mix it further.) Different color combinations can give you the effect of various semi- precious stones: for example, marbling several shades of green with white produces a clay that looks like malachite. Marbling earth tones and translucent gives the effect of agate. Pearl white with small amounts of dark gray and translucent makes a good marble. You can vary the marble effect by mixing the clay in different ways. Roll the partially-mixed clay out into a thin snake, or pull it, to obtain narrow streaks. Running it through a pasta machine one or more times produces a different sort of streaking. Repeatedly twisting and folding the partially-mixed clay strands can make an effect like natural amber. Once you learn how to marble the clay, try different techniques at different points in the mixing for subtly different effects. Experiment with using marbled clay balls into molds. They offer many variations that are beautiful with no painting needed.
