Laurie, I have not been a fan of cone 5/6 Laguna b-mix. I also had problems with cracking, (thrown work). I was convinced by a person who sells Aardvark clay to try their B-mix. I have to say that I have not had the problems with that. No cracking problems. Just thought I would share that. I live in Colorado also and there is now an Aardvark dealer on the western slope and I think a couple of places on the eastern slope that sell it. For handbuilding I have become a fan of Laguna Whitestone and 1/2 and 1/2. Both are nice to work with, little warping, very strong.
