We all have them, our special mug, our favourite plate, but the mug is chipped and the plate has a crack in it; that’s not such a bad thing is it?, well actually, yes, it is. Broken dishes can harbour bacteria and increase your exposure to lead; so my advice is to remove all damage crockery and make use of it elsewhere.
Recently I helped a couple declutter their kitchen and we removed a fair bit of broken china. After explaining the dangers of eating and drinking from these items, they were happy to let them go.
I recommend you go through you cupboards and remove all broken and chipped china and do something useful with it. Recently I made a Mediterranean Herb Bed with broken bits of crockery, some of which I removed from a clients house, they were very happy it was going to be recycled and useful.
