SPI Supplies® Agate Mortar & Pestle Sets

Applications in the kitchen


All mortar and pestle sets look alike when viewed from a distance. But up close and where it counts, they are anything but the same.

We address here applications in the kitchen, be it institutional or residential, and the real issue is one of porosity and the fact that food material can be trapped in pores (if present) which then become sites for bacterial growth. Agate, when compared to porcelain, essentially has zero porosity where as porcelain has very large pores. When using porcelain, the food material that is ground into the pores can not readily be removed with any know protocol except plasma ashing.

When agate is used, this source of bacterial and possibly pathogenic bacterial contamination is eliminated since agate essentially has not porosity and therefore there are no pores into which food material can be lodged. And therefore, there are no organic residues left behind which can then become breeding grounds for bacterial growth.

Consequently, we are proud to report that some of the worlds finest restaurant kitchens use agate mortar and pestle sets purchased from SPI Supplies for the fine grinding of spices, nuts, and other food materials.
