Enough powder to make 100 Litres of Bentonite Clay Mix (10x UK standard household buckets). The perfect solution for events where lots of mess is required ora larger container is to be filled such as a bathtub or pool.

What is Bentonite Clay (SBC)?

SBC is one of the most powerful healing clays available. Used widely in the horticultural, health & beauty, detoxification and cosmetic industries, SBC expands when wet, able to absorb many times its dry mass in water.

This feature makes it ideal for large projects on smaller budgets. Our Bentonite Clay is perfect for special effects such as full submersion in mud / quicksand, for example. Bentonite can be used in large containers such as pools & bathtubs as well as sprayed or poured.

SBC is odourless and should not stain. It is safe for consumption and full submergence. It is also safe for disposal in public sewerage once diluted with plenty of water.


Effect Uses:

Quick Sand, Cement, Mud, Clay, Gunge & Foods, Make-up Effects, Skin Treatments, Detoxification & Soaps.

The Powder:

Bentonite is a safe visual material for the film, theatre and entertainment industry. Supplied in polythene bags inside a large container ready for immediate use at home, in the studio or on location. Each bag you receive is enough to make 100-120 litres of Bentonite Clay.
