Do you have any of it left? If so would you be able to do me a favour as an experiment? Measure the diameter of a dry granule then put it in a jar of water and guesstimate as close as you can how much it has swelled over a certain time period until it stops swelling? I am curious as to the 'quality' of different sources/deposits of Bentonite and being able to compare would be valuable in doing so. (I find a fair gap in pricing and I am wondering if the 'deals' are only as good as the product received.)

Anyone else that could do the same and report here on the source and company they got the Bentonite from would be appreciated.

Bare in mind that swell rate is not as important as maximum size when fully saturated as the rate of swell has many determinate factors.
