This is what happens when I copy strait from the computer, without cheking
if I have entered it right.
ONLY one time titanium!
Checked again!
.... As you all know, the best inventions, are created in mistake, so Ron
wrote
in his recipe Titanian oxide, Insight, decided it was talc, I probably added
manually, the titanium., Not to blame insight!, anyway this explains me way
there was so much Titanium compare to the rutile, as from my experience,
based on Marty,s butterscotch, should be 10/5 or 8/4 to create yellow
glaze,so I am sending here now two glazes, Ron Roy,s to you to try,

> RR revision of Mary's Butterscotch c6
>
> Frit 3134 - 25.0
> Dolomite - 12.0
> Lithium Carb - 2.0
> G200 spar - 10.0 (custer will do)
> Ball clay - 26.0 (I used OM #4 - use what you have)
> silica - 25.0
> Titanian Dioxide - 9.0
> Rutil - 4.0
> Total - 113.0

And here a new glaze, based on the one I prepared, with correction of
rutile/ titanium, The different here will be that in my frit there is more
K2O than I could supply knowing your materials, so I used Cryolite and
supply Na2O , I am going to prepar it again, as well as the RIGHT conversion
of Ron Roy revision , and we see , I will paint my home with yyyyelowww
glazesssssssssssss!
