Denby stoneware is fantastically durable and practical and is designed to be used and enjoyed, but like all things of beauty need a bit of looking after in order to get the best out of it for lots of years to come. Whilst our stoneware products are dishwasher safe, constant dishwashing may result in discolouration over time so we recommend using low temperatures and liquid detergents. Also think about the poor items at the bottom of the pile which so rarely get used - why not rotate your stack so it all gets used evenly (and if you're very disciplined or have plenty of time on your hands then alternatively, wash your items by hand and dry with a soft cloth). Our stoneware is also suitable for microwave and freezer use for cooking, reheating and storing food, but please note that any pottery can crack when exposed to sudden changes in temperature so bring items slowly up or down to temperature where you can to avoid such cracks.
