Thank you @Rae Reich and @neilestrick for your responses! I did fire them again, some of them did flatten again and others didn't flatten enough. Lesson learnt!

Hello! I am creating small plates for a cafeteria and during the last of the glaze firings I wanted to be able to fit all of them in the same firing (they were only 2 left and didn't want to have to fire an almost emply kiln), so I used some of my columns as props to create different heights and intercalate the plates to fit them all in one. Ingenious me thought it would work. When I opened the kiln, the plates which were on top of the columns have slightly bent downwards. Does anyone know if I fire them again, this time flat, will they flatten again? Thanks!
