Notes
This is part of a program to compare the results of fluxing Alberta Slip for cone 6 using 4 different frits (3134, 3124, 3195 and 3249).
Frit 3249, used here, is a low expansion frit, it reduces the thermal expansion of the Alberta Slip base GA6-A (from 7.6 to 6.5), such that it works well on even P300 porcelain.
Even though this recipe calculates to a low Si:Al ratio and a very high MgO level (both indicative of a matte glaze), this one fires ultra glossy.
We generally add 2% iron oxide to darken the color.
2700 water, 3000 dry gives 1.43
