Obviously, depending on the final goal of the analysis (phase identification, polyphasic mixture qualitative and quantitative analyses, indexing, cell refinement, structural determination, etc.) the necessary level of "care" can vary and the time and costs of sample preparation and data collection can be .
Analysis by infrared spectroscopy (FTIR) An unsieved portion of the mortar sample of about 1 to 2%, relative to the KBr amount, was mixed and ground together with the KBr powder.
A mortar and pestle is a tool used to crush, grind, and mix solid substances (trituration).The pestle is a heavy clubshaped object, the end of which is used for crushing and grinding. The mortar is a bowl, typically made of hard wood, ceramic or stone.

Grind the anise pods, cloves, peppercorns, fennel, and cinnamon in a spice mill or with a mortar and pestle to a fine powder. Store in a sealed container in a cool dark place .
Grinding is widely used in ore size reduction. In this investigation, grinding is proved to be advantageous in improving the floatability of anthracite coal of mild oxidation.
Mortar is a workable paste used to bind building blocks such as stones, bricks, and concrete masonry units together, fill and seal the irregular gaps between them, and sometimes add decorative colors or patterns in masonry walls. In its broadest sense mortar includes pitch, asphalt, and soft mud or clay, such as used between mud bricks. Mortar comes from Latin mortarium meaning crushed.
