Mine is .78. I don't really know what the strontium calcium ratio would do for the glass. It's great in phosphates, no argument there . I do know the barium/Calcium one is spot one and make the clear absolutely brilliant moreso if there's a lot of potassium. .
I think another issue that hasn't come out yet Jordan is what the slow cooling of the mix does to the opacity. I would suspect it's a major influence. If you were pulling that from the pot, It would be really nice. Mine tend to strike in the lehr and really strike if annealed twice.
