Glaze Question - Strontium Crystal Magic in Clay and Glaze Chemistry Posted October 31, 2017 · Report reply Thanks for all of the advice. I went ahead and remade the SCM yesterday starting with a pint of water. I mixed them up and left them sit overnight. I will sieve them this afternoon when I get some time in the studio. I do have a spray set up ready to go, but I'll probably dip the first tests and maybe I'll do a few other tiles with something layered over the top just to see how they turn out.
