There is about a 1:1 ratio of ash to solidified remains. For example, if we receive 6 cups of ash, we will return roughly 6 cups of "stones". An average full set of human remains typically yields 40-80 stones ranging in diameter from about the size of a quarter to about 3” around. The average cat yields around 2-8 stones, and the average dog yields around 5-35 stones.
