Frequently Asked Questions


How does Garrison Minerals price their products, particularly Magnesium Hydroxide slurry?

Magnesium Hydroxide whether in a liquid or powder form is still a solid material. Magnesium Hydroxide should ALWAYS be priced on a DRY WEIGHT basis. Magnesium Hydroxide priced on a per gallon or wet pound basis is misleading. The difference in dry weight on a 58% solution verse a 56% solution is 1,000 dry pounds. If pricing is given on a gallon basis with a total solids variance of 55% – 60% solution — the customer could be paying more for water and less for the actual product. ALWAYS request pricing on a DRY WEIGHT basis.
