Step 1 — Ensure the glass mortar is clean, dry, and free from any previous material residue before use.

Step 2 — Place the required quantity of dental powder into the bowl of the glass mortar.

Step 3 — Add the recommended number of drops of liquid or catalyst into the mortar over the powder, as per the material manufacturer's instructions.

Step 4 — Hold the mortar firmly on a stable surface with one hand to prevent movement during mixing.

Step 5 — Insert the glass pestle into the mortar and begin grinding the powder and liquid together using a firm downward circular motion.

Step 6 — Continue trituration using circular or pressing strokes to break down all powder particles and integrate them with the liquid uniformly.

Step 7 — Mix until a smooth, lump-free, and homogeneous consistency is achieved as required for the specific dental material.

Step 8 — Use the mixed material promptly for the intended clinical or laboratory procedure before it begins to set.

Step 9 — Immediately after use, rinse the mortar under running water and wipe clean with a gauze or tissue to remove residual material before it hardens.

Step 10 — Disinfect or sterilize the glass mortar as per your clinic's or lab's infection control protocol before storing or reusing.
