I just meant that you should read that for the effects it will have on the rock (which isnt bad).
Not that you should actually "cook" the rock.
cooking the rock has nothing to do with heating the rock up... do some research on it and you will see what I mean. A basic run down of what cooking rock is: Keeping the rock in a lightless, yet normally heated, environment to stop the growth of algae (in most cases) for a period of 6-8 weeks.
