Our range of porcelain tableware is elegant and beautifully designed, which is luxurious but practical. Ideal for Restaurants and Hotels, it's fully vitrified to meet British Standards (BS4034:1990) to ensure they are Dishwasher, Freezer, Microwave and Oven safe with a high resistance to chipping, crazing and water absorption. However, although our Orion products are designed to withstand many pressures, please avoid where possible, sudden temperature changes (e.g. oven to freezer) as thermal shock may occur. The use of non-abrasive materials such as rubber or plastic utensils is recommended when removing excess food as metal utensils may cause lasting damage to glazed surfaces. Furthermore, it is not advised that you wash porcelain items with metal items (such as cutlery) in the dishwasher.
