Bentonite

Bentonite is a versatile, swellable aluminum phyllosilicate clay primarily composed of montmorillonite. Renowned for its extraordinary absorbency, it can expand significantly when wet, holding up to 5–6 times its dry mass in water.

Key Properties & Applications:

• Desalination & Restoration: Ideal for use in desalination compresses to extract salts from masonry.

• Oil Painting: Acts as an effective thickening agent. Recommended dosage: 1–5% of the total color volume.

• Purification: Used as a powerful adsorbent to decolorize and refine mineral, animal, and vegetable oils, fats, and waxes.

• Technical Spec: Our bentonite features a conductivity value of 278 mS.

Named by an American geologist after the Benton Formation in Montana, this clay remains a staple for its ability to attract and bind ions, fats, and oils in solution.
