Dang it! You've made a clay piece and it has been drying overnight and you realize after you left it uncovered and that you should have dried it slower! Well, you may be able to fix this. It isn't a 100% fool proof solution, however, this video will show you how to fix a crack after your ceramics or pottery piece has dried fully to what we call bone dry. We will be using vinegar and home made paper clay. Be sure to cover it with plastic after this process and dry slowly!
