I know what you mean. I think about it all the time too. I have DE here and that keeps me going but I still crave real clay.ALL THINGS CLAY
The second post is fabulous. Those cliffs are so white and beautiful. Just imagine if that was in your backyard we might go crazy. It is amazing that we are so attracted to the earth. How good it looks and How good it might taste. How we find such comfort in clay. They give so many reason why we should not have it then their are others who show its medicinal uses. I think it taste so good bcz of our bodies lack of certain minerals that we might over indulge. I do love clay I have not been eating as much as I use to but I do think about it all the time.I am fascinated that we just develop this urge and craving for this chalk like substance. Sorry to say I love chewing it.
Here's another picture. I think this is in an area like what Chalk lover talked about that it is not suitable for eating and has fossils in it but doesn't it look good?
That second link that I provided above says that in parts of Kent in England they have "very soft, nearly flint-free chalk, the Margate Chalk." That sounds good. It also talks about clays mixed in with the chalk. Wish I could be somewhere like that to dig around in the safe areas to try to find some of the good stuff!
