What is the average particle size of our clay?
To provide you with the finest powder possible, the mineral powder in our products undergoes a separation process into grades that meet the needs for various markets. The larger particles are removed and we keep only very fine particulate of differing levels of fineness. It is important to remember that as with all natural products, sizes vary. Traditional measurements of grade are inadequate for sizes as small as the particles in ION-MIN®. Unfortunately traditional measures of grade only tell you the largest particle sizes that have been removed from the product. However, most of the product contains particles much smaller. And as a consumer, you should know what the ratios of fineness are for each product. To find out how much of our material is ultra-fine, we analyzed ION-MIN® using a “Standard Test Method for Particle Size Analysis”. This standard method is issued under designation D22-63, (re-approved 1990), of the ASTM (American Society for Testing and Materials).
