large jade pebble-cooking stone
Native Americans in early California used jade pebbles as cooking stones. Due to
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.
