Just wanted to say "You are right"
Robert Clark,
Just wanted to say "You are right" about the color of these rocks. The more Robert works with this stuff the more they keep coming back blue. I had a bit of fun at your expense with the blueman on mars stuff. I apologize for that.
I think we have two different explanations, but you are so absolutely right:
It's Blue.
Owe you a beer:
Humbly,
jms.
