I have a antique ceramic mug that has a hairline crack inside about 5" long. I would like to know how to fix it so the crack does not show anymore. It is a Budweiser Holiday stein from 1981.
I just read an answer to this question on wikihow. It's quite detailed: http://www.wikihow.com/Mend-a-Crack-in-Pottery
Too complicated for me. Good luck!
