Application of kiln wash Issue with cracks

This is what happened to me. It does seem as though kiln wash can be finicky. I suggest you read through all the information on this topic on this site. It will help you to make sense of it.
You may start a new forum to address your topic directly??

I have never used store bought wash in 38 years-I have a bag of it someone gave me and it appears very cheap. No alumina in it. I think I'm giving it to our local ceramic supplier. I did read you added feldspar to yours (Kingman? custar? G200? S spar?-Nepheline syenite? or some other??)
I have no idea on why but either way I think you must have some oil or grease on shelve-have you bisqued them yet?? That will burn off contaminants
Ceramic process can be frustrating and problem solving is what its all about ( you are your own tech now)
This thread has some great wash formulas-make one up and toss out that cheap wash. Good wash costs $$ but equals great results.
My 2 cents

I will mix up my own batch of wash going forward.
