Agate is the preferred material for mortars and pestles for laboratory use. It is harder than glass and porcelain and has a very fine grain structure, so a previous grinding product can be cleaned out with ease to reduce cross-contamination.
Do not use agate with liquid nitrogen as it is liable to crack.
Sterilise with alcohol or other chemical, heat could damage the mortar.
Because of their natural origin, the agate mortars and pestles may vary slightly in appearance from the picture.

Physical properties of agate
Chemical composition: 99.9% Si02, which makes it a quartz species, with trace contaminants alumina and iron oxide common
Class: Tectosilicate
Crystal system: Hexagonal-R; 32 (trigonal-trapezohedral)
Crystal habit: Usually as banded or layered botryoidal masses with microfibrous structure
Zoning: Colour banding and layers of inclusions are common
Specific gravity: 2.57 - 2.64
Mohs hardness: 6.5 - 7
Index of refraction: 1.53 - 1.55
Birefringence: Weak, 0.005 to 0.009
