Modified Lorio Ash tests

I unloaded the kiln this morning and saw my modified lorio ash glaze. It had the colors I was after but man did it blister. Tons of bubbles and blisters. It wasn't pretty.

So let's rework the formula.

Alberta Slip 43.5
EPK 13.9
Whiting 29.6
Wood Ash 13.9
Rutile 10

I suspect the rutile is causing the issue. So my next test will lose the rutile, replacing it with RIO and TiO2

Alberta Slip 43.5
EPK 13.9
Whiting 29.6
Wood Ash 13.9
RIO 3
Tio2 6

I also want it to run a little more than it is currently running so I am going drop the EPK down and add more flux.

Alberta Slip 43.5
EPK 5.9
Whiting 29.6
Wood Ash 13.9
Grestley Borate 8
RIO 3
Tio2 6
