My preferred method of cleaning for the longevity of your pieces is by hand, using a mild dish detergent and non abrasive sponge. However, my pottery can withstand the dishwasher ~~with some risks, knocking into another piece or reckless handling by that clumsy family member (we all have one 😉). Of course pottery is breakable, it will not survive falling off a tall building. Care should also be taken not to expose your piece to extreme temperature changes (example: refridgerator to oven, hot liquid into a cold mug etc.) as this could cause thermal shock. Most of my pieces are microwave safe, the exception being any piece with Gold or White Gold Luster, these are definitely not safe in a microwave and will me noted in the product description. With simple easy care your pieces will retain their beauty for many years to come.
