Interesting. Thanks for posting.
Have you seen this?

...and quintupled (at least) in price.
Now that I know what I can get paid, I’ll never work again! ;’)
I imagine that a lot of volcanic ash is available in Washington State (Mt. St. Helens). I know that they make very pretty art glass there from some of the minerals that were spewed about during the 1980s eruption when the top of the mountain blew off.
I was watching a program on either the Smithsonian Channel or one of the History channels the other week, and they stated, during a discussion of Roman concrete, that one of the ingredients in their underwater concrete was a fairly large quantity of animal blood. I’m not sure how it works, but it was supposed to allow the concrete to harden under water. They built a harbor at Cesarea with it. I asked my son, who has a PhD in Materials Engineering, and he didn’t know what properties blood would bring to the mix.
Truly amazing.
