Agate Mortars are made from crystalline precious stones which, due to their structural conditions, are suitable for fine grinding procedures, communication processes and mixing of middle-hard up to very hard substances. The high degree of chemical purity of the agate (99.91% SiO) means that no impurities enter the sample during grinding.
A further advantage is the exceptional abrasive resistance of this natural gem. All mortars have a symmetrical octagonal shape and are exacting in design and workmanship and come with a suitable pestle.
