Usage Instructions & Precautions
Strictly prohibited from contacting hydrofluoric acid (HF).
Avoid sudden temperature changes (thermal shock). If drying in an oven, the maximum temperature must not exceed 400°C.
For large blocks or crystalline samples, crush them externally first before placing them into the agate mortar for grinding.
Do not grind materials that are excessively hard or have very coarse particles — this may scratch or damage the mortar surface.
During grinding, place the mortar on a stable, non-slip surface and keep the pestle vertical.
Large solids can only be crushed, not pounded with the pestle (to avoid damaging the mortar/pestle or causing spillover).
For explosive or highly corrosive substances, cover the mortar surface with thick paper or plastic film, make a small hole in the center, insert the pestle, and grind carefully. Never fill more than 1/3 of the mortar’s capacity.
After use, clean with water. For stubborn residues, first wash with dilute hydrochloric acid, then rinse thoroughly with water. You may also add a small amount of table salt and grind lightly before final cleaning.
