Snowflake crackle glaze

I was wondering if anyone knows of any commercially available snowflake crackle glazes. I’ve seen some beautiful examples online, but most of what I’ve found involves making your own glaze.
I’d really prefer to buy a premade glaze because, to be honest, I know basically nothing about glaze chemistry. I’d love to learn someday, but I have no idea where to even begin, and I’m definitely not experienced enough to start mixing my own glazes yet.
If anyone knows of companies that sell snowflake crackle glazes, or even glazes that create a similar effect. I have already tried kiln ice from amaco and it was relatively nice with a little issue on evenness and thickness even after applying 4-6 thick layers, I’d really appreciate any recommendations. And if anyone has advice on good places to start learning glaze chemistry as a complete beginner, I’d love to hear that too.
Any help is greatly appreciated. Thank you!
