The playful and practical Oiva (superb) dishes are made from vitro porcelain, a high-fired and high-class material. Thanks to the high firing temperature, the surface of vitro porcelain is impenetrable to liquids and foodstuff.
About proofness
The dishes are dishwasher, oven, microwave oven and freezer proof. We recommend avoiding drastic temperature changes, as this may cause dishes to break if chipped. Please bear in mind that the Oiva dishes are not suitable for cooking food on the stovetop.
