Celebrating 10 years, Denby Halo is one of our most popular and Instagrammed collections with its captivating glaze reaction. The two tones of glaze combine to create a dramatic effect that reflects our time-honored know-how. Like all of our stoneware, they're covered by a ten-year guarantee and are a long-lasting conscious choice for your home. Use and care: Stoneware clay is very strong. It is fully vitrified (the surface is made glassy and non-porous) which gives it strength, durability and chip resistant. Dishwasher - we recommend using low temperatures and liquid detergents. Oven and Microwave – for cooking and reheating food. Please note: Using microwaves as a means of warming empty dinnerware can cause damage to both your dinnerware and microwave and is therefore not recommended. 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.
