For this mortar the ceramic pestle head is so designed that roughness, which provides the necessary friction, consists of concave indents. The edges of the extensive indents are ground sharp. This particular form facilitates the grinding process and ensures that nothing remains sticking to it. The sensitive ceramic is only used for the pestle head and the interior of the mortar; the rest is made of silicone.
