The 27cm Rimmed Dinner Plate is large with a thick raised rim on the outer edge. This plate can either be placed on top of the dinner plate as an accent piece, or standalone for smaller-portioned main courses. Bone china can be washed in a dishwasher - at a maximum temperature of 140°F. However, we would recommend hand washing any pieces with gold or platinum precious metals. Stubborn stains can be removed by soaking in a mild bleach solution for up to one hour without damaging the china. Scouring pads or abrasive washing agents must not be used. Tableware with a gold or platinum trim must not be used in a microwave.
