No.
But I do have a chalk-question, and you are now the appointed chalk-expert. So here it is:
This geological chalk you're talking about. Is it the same as colloquial chalk? Like the stuff used by teachers in classrooms on chalkboards?
If so, is there any "chalk shortage" coming about from all the teachers using it up... what with it taking so long to make more, anyway.
Just wondering.
