4 Color Marbled Clay

White Stoneware, Mason Stains
Laying out the stain on my table. Sprayed to dampen.
Wedging in the green. It takes a long time, especially to completely mix in the stain.
Keep wedging, and wedging, and wedging.
The colored clays after 45 minutes of wedging in the stains. Each ball is about 1 kg.
A cross section of the layered clays. To layer, cut small slabs from the colored clays. Stack them up and pat them together. Try to avoid adding in air bubbles.
After layering the clays, I like to give the layered ball of clay a quick couple of wedges to striate the layers. After you've striated the layers, you have a lot of options for cutting open the clay to reveal different patterns.
