It says that early lithography used limestone.

Here too you get pretty much an idea as to how it works and what sort of stones lithography uses:

Thanks for the links.

If those are indeed limestone, I suspect they are not overly expensive (couple of 100s for a new stone similar to mine.)

If the knife test turns out Ok I might have them cut into norton sized blocks for convenience.
