Insane Reefer,
Are you still baking your rocks? I've let my rocks sit now for 48 hours and am trying 2 different baking techniques.
In technique one, I took the rocks right from the mold box to the BBQ set on high for 3 hours. After that I let it soak for 2 hours.
In technique two, I took the rock from the molding box and went into a soak for 2 hours to pull out as much salt as I could. From there I went into the BBQ for 3 hours.
Right now it seems like technique 2 is working best as technique 1 rocks seem a little brittle. If you are still baking your rocks, what process are you using?
I'm using the following recipie: 1.5 parts cement:1 part oyster shell:3 parts salt.
Thanks,
Steve
