Paul, I wouldn't think a longer firing would make that much difference in
this glaze. My first question to you would be, are you using the same
chemicals that you used in the other kiln? I'd bet you're using a different
rutile. True?

Rutile Blue
cone 10 Reduction
Dolomite 15.8
Custer Spar 30.0
Whiting 11.1
EPK 16.8
Flint 26.3
Rutile 8.0
I would like to know how what kind of firing schedule others are using with
this glaze, and how it is coming out. The kiln i used to fire, a natural
draft kiln, took up to 16 hours to fire with a long soak and a slow ramping
down, and i finally got this glaze to come out a dark, variegated blue that
looked really interesting. The kiln was fired in heavy reduction.
With my new forced-air kiln, it reaches cone 11 much faster, like 7 to 9
hours and even with a soak and a fire down, this glaze comes out a dull
white, sometimes with just a slight tint of blue.
I'm thinking it may just need a longer firing, but i know a lot of people
have used this glaze. Can anyone explain what they do to make this glaze
turn out nice? Thanks,
Paul B
