Bentonite Clay

Solubility & Behavior in Water

Not soluble.
Instead, swells significantly, forming thick gels.
Thicker in cool water; looser in warm.
Absorbs oils readily; forms stable pastes and poultices.

Compatibility & Pairings

Pairs beautifully with:
• Arrowroot or rice powder
• White or pink kaolin
• Aloe vera, hydrosols
• Marshmallow root, chamomile
• Dead Sea salt (for detox)
• Magnesium chloride (for softening)

Shelf Life & Storage

Indefinite when kept cool, dry, and airtight.
Keep moisture out of the jar.

Safety Notes

• Too strong for very dry or reactive skin
• Avoid inhaling fine powders
• Do not store hydrated clay in sealed containers (expands)

Volcanic Earth • Strong Drawing Power

Key Minerals & Constituents

Rich in:
• Magnesium
• Silica
• Calcium
• Sodium
• Trace minerals
Known for its ability to bind oils, toxins, and excess sebum through an electrical charge that increases when hydrated.

Preparation & Best Practices

• Sprinkle gradually into water to prevent clumping
• Allow time for full swelling before use
• Hydrate with hydrosols for softer slip
• Use non-metal bowls for maximum charge (not dangerous — just optimal)
• Pair with aloe or kaolin to soften intensity
