Tried a firing and slow cooling with my current cone 6 glazes. I have a=20
small Scutt 818 with a controller. This was my schedule:
Ramp Temp Hold Degrees/hour
1 200=BA 200=BA
2 2000=BA 400=BA
3 2190 20 150=BA
4 1500 100=BA
Unfortunately, this firing schedule was a little too long (probably the hol=
d=20
time) for my kiln. The cone packs indicated it went to cone 7 (tip all the=20
way down).
There was no difference in the following glazes (all of which are in the=20
archives)
Falls Creek Shino & RR Green=20
The RR Sapphire Blue started to run.
Revised Xavier's Warm Jade Green was a lovely green and has usually been blu=
e=20
before.
Stonehenge had the most change. It has been a hazy blue gray and now was a=20
mottled matt tan with brown speckles.
The biggest surprise was a salt shaker that had white engobe and white glaze=
=20
over it. It turned a mottled yellow to brown semi-matt. These were both=20
commercial preparations from the same company. No idea why, but won't persu=
e=20
it since I don't use them often.
These were all over a dark tan stoneware.=20
Am going to try Ron and John's glazes next and then some revisions of my own=
