The only way is to buy it from the company that mines Pascalite in Wyoming. But you have to buy it in quantities to get it at wholesale. Remember, volume discounts are given only when the volume bought is large. Do not expect to get wholesale or below wholesale if you only want less than 50 pounts.Ebay is the second place that has good prices. But the problem with Ebay is that the clay you might receive may not be 100 % Pascalite because it is easy to mix in cheaper clays without anybody seeing the difference.
