I just unloaded my bisque, and every piece that was thrown with B-mix Sand cracked, save two small salad plates. Not s-cracks or cracks along the foot ring; these cracks started at the rim and meandered. Sadly, the casualties included the vessel sinks. Was I raving about B-mix Sand before? I take it all back. Doesn't matter how easily it throws if nothing survives the bisque.
I didn't dry or fire especially quickly, and every other piece in the kiln survived just fine.
Good thing I am so very mild-mannered, or I'd be really aggravated right now.
I think I'll go have a drink. Maybe do some yoga, or something.

Very sorry to hear that, especially about the vessel sinks. I was really interested in seeing how they'd turn out. I was asked to make one last summer but was too intimidated by the whole plumbing fit issue.
what a bummer, I had problems with B Mix cracking on rims when I used cone 10 and some with cone 6 too, I use Macabee 5 now, of course that's cone 5 and I am assuming you're using 10.
Well that just sucks :(
You are a better person than me...I'd be either crying , smashing the bisqueware, or taking it out on my husband!
Wish I could offer insight, but have little experience with B-Mix. Instead I'll offer sympathy and a cyber hug!
never heard of bmix sand?? is that bmix with grog? i have used bmx cone 10 for decade! never heard of this problem. i do use regular bmix, no grog or sand. did you add sand? that would be the problem if you did. sorry to hear about your loses.
Hehe. No, Shane, I didn't add the sand. Laguna sells the body that way. I, too have used regular b-mix, with only minor cracking issues, mostly solved by drying even more slowly than usual.
Never had any real problems with B-Mix cracking, other than things I attribute to my own mistreatment of the clay in throwing or trimming. Like Shane, I have never heard of B-Mix Sand. Drying to fast at the rim, maybe??
