  1. I am an experienced potter trying to find the right porcelain for my work. As of late I have been using cone 6 Laguna 15 because it is super white and super vitreous. Both of these things are important to me because I leave much of the exterior of my pots unglazed, so the porcelain needs to look very white and not stain from absorption over time. However this clay cracks like crazy!!! About 50% of the mugs I make have cracks around the handles. Also, lots of cracks along the bottoms. I have tried everything I can think of to prevent cracking- compressing like CRAZY, adding more clay to attachments, different glaze/clay combos, slower firings with holds... at this point I’m wondering if it’s me or if it’s just the clay. Has anyone else had this problem with Laguna 15? Has anyone found alternative super white, vitreous clays that don’t have cracking problems? This clay is so beautiful I wish I could figure this problem out, but a 50% loss rate is too high!
