This porcelain is food safe and can, with some care, be used in the oven, microwave, and dishwasher. Sudden changes in temperature (eg. from freezer to oven) are likely to cause thermal shock, which will damage your porcelain. Always place very hot items onto either wood or cloth. To avoid glaze scratches, mud porcelain should be stored in plate racks or with linen/felt between each item.
All mud australia is handmade in their Sydney studio. Irregularities in size, glaze, and texture reflects the many human touches received during the making process and should be embraced.
