Use to dry flowers or to extract moisture from any object. Silica gel absorbs moisture and can be easily dried out again. Leave on a warm radiator to dry out. Contains 10% indicating crystals, orange when dry and green when wet. Crystal size approx 0.5mm to 1.0mm. The gel can be used as it is in the canvas material sachet provided to absorb moisture. NON Toxic. Our silica gel does not contain cobalt. It will absorb up to 30% of water by weight and can dried out many times. Indicating granules may lose colour over time, but will still be functional.
