On arrival, most of the stone was pumice stone and 9 stones were other non-porous stones. The total weight of the non-porous rock was about 80 grams, which means that 8% of this product is unusable. The stone cleans well and will not crack or break when heated at 450F for 1 hour. Overall, this is a decent carrier with a good finish. Note that some of these rocks will float for a while, so don't plan on using them in places where they can float away or get stuck in pumps etc.
