Has anybody pressed a full crown in the Opal ingot. I have an over bleached #7 over zirc abut that is blue/white trans. Just a thought, nothing else matches.
I've done it, the Impulse 01 is the "bluest". Hard to do much to bring the value up though, if you need to. Your might try layering T/b or OE1 on an HT that's close. Good luck1
