Agate Mortars & Pestles Description

Agate is a natural form of chalcedony with a Mohs hardness of 6.5–7. It offers excellent wear resistance while virtually eliminating sample contamination from the grinding tools themselves. This makes agate the preferred material for laboratory grinding of minerals, chemicals, pharmaceuticals, and dried herbs, as well as for fine food preparation in professional kitchens.

Each set is handcrafted from natural agate with polished grinding surfaces. Minor natural cracks, color variations, or slight translucency differences are normal and do not affect grinding performance.

Agate Mortars & Pestles Packing

Our agate mortars and pestles are carefully handled and individually packed to minimize damage during storage and transportation, preserving product quality in original condition.

Precautions

Avoid Contact with Specific Substances:

• Extremely hard substances: Do not grind to prevent damage to the mortar and pestle.
• Hydrofluoric acid: Avoid contact to prevent corrosion damage.

Operational Details:

• The mortar should be placed on a stable, non-slippery surface.
• The pestle should be kept vertical during use. Large solid pieces can only be crushed, not pounded with the pestle, to avoid damage or splattering.
• Explosive substances should only be gently crushed and not ground.
• When grinding substances corrosive to the skin, cover the mortar with a thick paper or plastic sheet, cut a hole in the center, and insert the pestle through the hole before grinding.
• The amount of solid in the mortar should not exceed 1/3 of its capacity.

Usage Restrictions:

Agate mortars cannot be heated and must not be placed in an oven for drying.

Cleaning Instructions:

• Rinse with water first.
• For acid-resistant mortars, dilute hydrochloric acid can be used for cleaning.
• For stubborn residues, add a small amount of table salt, grind it, and then clean the mortar again.
