There are a few things that can cause raku to explode in the kiln. One is firing the pieces at too high a heat too quickly. Some types of clay also fire better than others. In raku, course or groggy clays seem to hold together better than the denser or finer clays. Other culprits may be glazes that are not dry, or placement. The pieces should be placed so that the flame is not directly hitting them.
