Our porcelain is food safe, and with care, also dishwasher, microwave, oven and freezer safe. Hand washing is recommended for larger items. Oven use only up to 220 degrees Celsius, not intended for baking. Avoid sudden and extreme changes in temperature that could result in thermal shock (e.g hot oven to cold water). Always place very hot items onto timber or cloth. Store with linen/felt between each item to avoid glaze scratches. Do not stack like items. Wash before first use.
