Thank you for the question. According to the text : " Avon's 1876 Cape Cod Collection Glass Dinnerware" by Debbie and Randy Coe :
" The glass is not designed to withstand the intense heat of a dishwasher. It is not heat resistant and cannot be used in a conventional oven nor in the microwave oven."
And Just in case you were interested in cleaning information:
" The glass needs to be hand washed with regular dish soap"
I hope that this helps
