All Mud Australia is handmade in Sydney, Australia. Slight irregularities in size, glaze and texture reflect the artisan nature of the product and should be embraced.
The 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.
