You have heard of sand and carbon filters. It might be interesting to have a filter made that had embedded pascalite clay in it. Silver is another substance that I would add to a filter for killing germs. I almost got into the water filter business, after I returned from living in Mexico. A pascalite bath is an interesting thought and the bonus is that there would be no mess. Thanks Lapis. I thought about your post in a mini vision this morning. I wonder if the pascalite could also help with bags under the eyes? I am getting excited, while I am waiting for my my clay to arrive.
