Bright Green Cone 10 Glaze

I should note that I do have an 80's fashion, oh-my-god-green that is so unnatural I can't stand it. But my students love it, so I will share it to get this topic started. Plus the formula appeals to my sense of organization as the ratios are 1,2,3,4:

Cone 10, Redux
Gloss, Opaque, Viscous, Bright Spring Green
Best on iron clay such as Rods Bod or Death Valley which creates dark flecks and variations in the green. On white clay the glaze is solid, unchanging, blindingly bright green.
