Porcelain. Microwave and dishwasher safe. Do not overheat in the microwave or heat without water. Wash with care. Do not use abrasive cleansers or steel wool. Product size and shape varies in each item due to manufacturing process. Appearance of color glaze unevenness varies in each item. Some products may take on scorched-like texture on the surface. It is an unique glaze effect called "yo-hen", unintended color transformation show on the ceramic and porcelain after firing.
After use of metal utensils, gray marks may become noticeable on the surface of tableware. These are called metal marks, and they are caused by the friction between porcelain and metal. To remove them, we recommend using a soft cleanser such as Bar Keeper's Friend and gently rubbing with a wet cloth or sponge.
