Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.

The Greeks used a really weird type of clay called the tiygu. This clay is very soft until fired then it becomes harder than most clays. The Greek, sometimes, also use a clay called dertiu which is a very rare clay found in Canada. This type of clay is very hard and only some of the more experienced Greeks could make pots with dertiu clay>
