These vessels have been coated with a water-based quartz sealer (otherwise known as silicon dioxide or SiO2) that inhibits the growth of mould, algae & scale, repels water & other liquids, & minimises the staining caused by fats, acids & alkalis. This revolutionary sealer creates an invisible barrier between the ceramic surface & the food upon it, is thermal shock resistant & so is commercial dishwasher, microwave & oven safe up to 450°C. There is no need for harsh commercial detergents when cleaning, in fact reducing contact with solvents, abrasives & chemicals will prolong the life of the coating. It is highly scratch resistant & has been tested for food safety compliance to German food safety standards. These unglazed vessels are the first of their kind, the only unglazed food-safe ceramic ware on the market.
