Also the cells on the mold side seemed to crush/pop on their own once pulled from the mold under atmospheric pressue. \ I was thinking that a 8-10lb density would be better for shaping and then surface finishing. Any thoughts or suggestions?

Will just pour it into ice cream containers to make my own blocks, gives me a much better density for patterns. Thanks for the reply though Matthieu!
