The main reason the red and white bodies behave so differently is their clay content. Terra cotta bodies are usually 85-90% red clay plus 10-15% ball clay, and sometimes a little grog, so almost entirely clay. Low fire white bodies are only about 50% clay. So their workability and drying times are totally different. It's just their nature.Web
