Bubbles and Mocha Diffusion

This is a demonstration workshop where you will learn the chemistry and applications of two techniques that lets natural phenomena take over to give stunning surface designs on your pottery.

The bubble technique involves mixing soap with underglaze or glaze and then blowing air through a straw into the soap mixture to create bubbles that float onto your bisqueware then pop, leaving a bubble pattern. Mocha diffusion makes use of a chemical reaction that occurs when you drop an acidic solution of ceramic pigment onto liquid clay slip. The pigment grows into a dramatic dendritic pattern on the slip reminiscent of a tree or fern.
