Review: Good for making crystals - I got this for my son to use in a crystal growing science project. I don't really have any way to test the purity of it, but it looks and behaves in the right manner. The container was well labelled. I was a bit surprised to see that it did not have a secondary seal under the lid, but it showed no signs of degradation or significant clumping.
Review: received! - undamaged and in good condition
