[QUOTE="RockRat, post: 441290, member: 12682"] Clay is a charged particle, produces a negative charge ie binds together, the bane of every alluvial gold miner. Here is a small test you can do. Roll some clay into a ball, golf ball size, Place into a jar of clean water, ideally rain water or distilled water. Leave the jar over night, don't touch it. When you check it in the morning, and you find the water cloudy and the clay ball partially or wholly dissolved, then the clay is dispersive. go buy a lotto ticket. If the water is still clear and the clay ball is looking at you with a smiley face, you up ship creek without a paddle. So back to the cloudy water, add Gypsum as Goldilocks suggested, how much? you will have to experiment. What happen is the Calcium in the Gypsum releases positive charged ions (cations) which bond to the negatively charged ions ( anions) and stops the clay from sicking together. hope it works. have fun, :rainbow: [/QUOTE]
