An example of splitting, where a thrown clay develops a crack during, or minutes after, throwing. This often happens with clay bodies that have a wide range of particle sizes, for example those made from native clays not ground to 200 mesh. The larger particles create networks into which water can penetrate and begin and propagate a split. It is wise not to leave water or high water content slip on any surfaces experiencing tensile stress during forming.
