As long as they are both 06 glazes I don't think that would be a problem that would cause a crack. A tiny air bubble can crack a mug. When I am pouring my slip into the mold I am hitting the outside of the mold with a rubber mallet to move air to the top and out. I've never had anything crack. I do always fire at a slow ramp which may not be available to you in class. I also always hold for 15 minutes at the end of bisque fire to make sure the object gets to shrink its maximum amount. Your mugs are terrific so I hope you can solve this problem. (: Wendy
