Any tricks for glazing?

I’m newer to ceramics and was wondering ig there is a good way to know what the color will change into at higher firing temperatures? Like so… Question: “what color does green turn into when fired at cone 10” Answer: Blue

Another question i have is, is there a specific order to glazing? i overheard someone in my class say that you have to put shine coat on first because it will bubble and will harden like that.
