Oooopppss . . . several people have pointed out my error. Of course I should
have said China Clay, not chalk and my apologies for getting it wrong.
Having been to the Wheal Martin museum a few times you would think I could
get it right.
Certainly worth someone contacting NASA to get their description amended.
Sorry again & cheers to all
Roger
