Reply To: dial cracks

Hmmm… Cleaning the enamel to disguise hairlines may be some sort of use if you don’t care about item value. The hairlines will still be there and will get visible again as time goes by.
If you search the net you’ll find some good enamel restorers for the most valuable clock dials. They know how to prepare the dial and put it in the very hot stove. The enamel melts again and cracks and hairlines disappear completely.
