This is an interesting Chinese ornate blue Cloisonné incense plate (for cone incense) with a rotating plate and a pot to dump used ash into.
This was once an ash tray and can now find new life holding incense and making cleaning up ashes a simple affair.
Made of copper, copper alloys and vitreous glass enamel.
Having been carefully displayed for nearly five decades since acquired by a dedicated local collector, it remains in fine condition.
