Flux Test

This flux test was inspired by Greg Daly's "Glazes and Glazing Techniques", chapter 4, “Choosing alternative destinations”, p. 54, “Flux substitution”, in which a glaze’s primary flux (in this case calcium) is swapped for alternatives. As a typical example, in a calcium-fluxed glaze you can replace all of the CaO with zinc, barium, magnesium, strontium, or sodium/potassium. In this example, I've replaced the calcium with magnesium.

All of the flux tests can be found in this Glazy collection: Flux Test
