Before we get started I just wanted to say that this is my method for looking after ceramics, if it doesn’t work for you then feel free to disregard my advice totally!
Ceramics are created to be used, eventually they need cleaning to keep them looking shiny. Some pottery pieces will require more tender loving care than others but if you look after them they’ll last for years to come.
Dealing with cracks
If you gently chime your piece of pottery using your finger it should make a high pitched ringing noise. If it doesn’t then you’ve got a crack, its up to you to decide if you can live with this or not. From a hygiene point of view cracks in a pot can be breeding grounds for bacteria, so it might be better to get rid of these.
Dealing with chips
Chips in pots have similar problems to cracks. Chips can equally pose a health hazard and a risk of personal injury, these are best thrown away.
