I have played around with strontium cm Warm a little bit. I have not had trouble with running yet. I have brushed it on pots, dipped it, and blown it on with an atomizer. I like the blown on look the best. usually I have the heavier saturation of it near the bottom. If ever in doubt put it on a cookie imo. You never know unless you fire it. I have used it mostly under commercial glazes to test out how it changes things.
The mug and bowl is with it blown under amaco's new celadons in "ice". You can see the scm makes it white in those areas. (it is a brown stoneware clay body)
