    Exactly what I needed to make egg geode
  • Karen

  • I've been trying to create my own Prof. Figgy kit to make an eggshell geode. For that I needed potassium aluminum sulfate and this company had exactly that. The website was easily navigated, and I received it several days after I placed the order. An added plus was the fact that it wasn't overly packaged -- a small box, the product, tiny amount of packing material. All in all, a very satisfactory experience. Even though I don't have children, I'm going to look at the other items this fun company offers.
