A color blend is one of the best ways to see what a single base glaze can do. You mix one base, split it into small batches, add a different colorant to each, fire them, and study the results. In this clip from his best-selling video Understanding Glazes, John Britt shares his simple system for setting up a color blend, and explains how to read the tiles once they come out of the kiln.

Watch the clip, then mix up your own blend using the recipe and colorants in this post. - Jennifer Poellot Harnetty, editor
