Has anyone figured out the chemistry of the green phase of this
glaze that appears on horizontal surfaces?

Ferro frit 3134 33.5g
Ferro frit 3195 26g
silica 23.5g
OM-4 ball clay 17g
red iron oxide 12.5g
titanium dioxide 1g

No copper, chrome, or anything else like that. I get the same
result with EPK and oxides rebalanced.
