All MUD Australia porcelain can, with some care, be safely used in ovens, microwaves and dishwashers. When stacking in the dishwasher please be careful to avoid over-stacking.
Sudden changes in temperature (eg.from freezer to oven ~ from oven to cold bench) is likely to cause thermal shock, which will damage your porcelain. Always place very hot items onto either wood or cloth.
To avoid glaze scratches ideally your Mud porcelain will be stored in plate racks or with linen/felt between each item.
