Experiments with Cabbage Tree ash

The cabbage tree produces leaves that take a long time to break down, to me this indicated that perhaps the leaves had good amounts of silica in them, but this is not the case. However each test of this ash results in crusty deposits randomly placed across the surface. Almost a wood fired effect in an electric kiln. This is the sort of surprise that makes it worthwhile trying out these things.
