Denby 29cm Heritage Orchard mixing bowl is made from stoneware. It is a stylish addition to any table. Orchard is one of three patterns within our new Heritage collection. Generously proportioned with a few quirky Denby twists, each piece has a homely quality with a relaxed kitchen making it a joy to use. Stoneware clay is very strong. It is fully vitrified (the surface is made glassy and non-porous) which gives it strength, durability and chip resistance.It can be safely used in: Dishwasher: we recommend using low temperatures and liquid detergents. Oven and microwave for cooking and reheating food. Using microwaves as a means of warming empty dinnerware can cause damage to both your dinnerware and microwave and is therefore not recommended. Freezer: for storing food.All pottery and china can crack if exposed to sudden changes in temperature, no matter how strong it is, so please don't take items from the freezer and put them straight into the oven or microwave. Please do not expose to direct heat sources such as the hob or grill.Made in England.
