Let the dish come to room temperature first to prevent cracking. In the dishwasher, use a gentle cycle and space the pieces carefully so they do not bang against each other during the wash.You should test an individual piece on a low setting first, as 1960s ceramic compositions can sometimes heat up unevenly in modern high-power microwavesVery good condition.  I do not see any flatware scratches.  The back of one of the saucers has about a 1/2" chip on the foot.  Foot shows a little wear.  Please review Item Specifics  and pictures carefully.
