why oh why don't they just stay pristine..?? They start getting cracks and start having dark lines, and then they eventually crack. Is it just me?? Am I doing something wrong??

i have had a beautiful denby set for years and i put them in the oven on too hot a setting. Now all the centres of the dinner plates look dark and scratched. My fault as i cant stand cold plates
