4" Brazilian Agate Mortar and Pestle (Extra Deep) Item# AMP4d
This 4" extra deep, octagonal mortar and pestle are made from polished, high purity agate. They are handcrafted from the finest translucent, blue-gray natural Brazilian agate stone. They are resistant to acids (except HF) and solvents and are ideal for use with unknown chemical substances including samples for ultra-red, infrared, and x-ray fluorescence.
Whilst virtually unchanged since the Stone Age, the mortar and pestle is probably the most ubiquitous of all laboratory tools, helping ancient healers to unleash the curative properties of plants. In addition to its inherent beauty, agate is one of the finest natural materials available for a grinding surface. It’s virtually non-porous, so bacteria and contaminants have difficulty lodging below the surface. Agate mortar and pestles are used for laboratory work where cross contamination must be avoided at all cost. This is why finest kitchens use them for grinding herbs and spices.
