Help! Our Corelite shelves ( 1" X 18" X 18" ) cracked in half
during firing. Not all just a couple. Cone 10 reduction.
Anyone have this happen?

I've fired to cone 10 r quite a few times and have not had an issue. Is it possible something bumped them or something while in storage? Did they absorb water and froze, just guessing now.

I have heard of some cracking with New ones from a few reasons-Bad batch from Factory and as mentioned wet or frozen ones.

Are you storing them when not in use laying horizontally or vertically?

Thank you all for responding! I just cracked the door today. It's a car kiln. I could see that a couple on top cracked , no broke. I did not load it. I fired it. I will be unloading with my class Thursday. Then I can investigate further. They were out all winter but under cover. I'm in Colorado. :-). I'll let you all know what I see. I do know it went to cone 11.

As these where on top my thought is they got hot fast and had water in them hence the cracks.

You should store them off a concrete surface say up on wood to keep them from weeping up moisture during the winters

My advancers are out but under cover always but also up on a two x frame of wood with zero issues.

Also stored vertically

It happens to everyone at some point. I've unloaded a couple of kilns where the pots were holding up the shelf. Happened in college- once with old shelves, and once when a post from the salt kiln melted. Another reason it's good to have your pots only a tad shorter than the post-  the shelf can't fall very far when it breaks!
