large jade pebble-cooking stone
California
Indians in early California used jade pebbles as cooking stones.  Due to the clay
of good pottery clay, containers were baskets sealed by tar or tree pitch.  Water
and items to be cooked were added to the baskets along with jade pebbles that
had been heated by a campfire.  Only pebbles of jade would not shatter when
placed in cold water.
