There have been several posts over the past few days critical of "us"
electric cone 6 ers attempting to mimic cone 10 reduction fired results.
Hey,, you cone 10 ers,, let us have our floating blue and stop trying to
mimic our results!!!
Just kidding, if you like it, do it!

Thanks everyone for the help and ideas you sent regarding the kids class I
started, we are all having a great time. One of the boys told me 3 times
last week " This is Fun!"

Yesterday I fired a kilnload of blues, greens, mauves and Pinnell's reds
with a few Leach Whites ...... plus Mary's Floating Blue R ^8-10 from
Hal's Glaze of the Week for August (archives). The kiln's still too hot
to open (afraid of crazing) but I did pull out a small, test bowl with
the Floating Blue. It IS nice. I fired to ^10 tipped and reduced, and
an oxidation soak for about 20 minutes at the end. The bowl is a soft
blue/grey where the glaze is thicker, with sky blue where thin (on the
bottom third where I'd scraped and sponged the glaze hoping it wouldn't
run). There's some breaking brown on the carved edges... and swirly
wisps of light, light tan in the inside bottom where pooled. I'll fire
this glaze again.
This is what Hal said about the FB in his notes:

It seems only yesterday I remember Joyce having trouble firing
the kiln.......
now she sounds like a pro. You've come a long way baby!

OK, so why did I get a plain ole brown. I fired Floating Blue on a white
stoneware to Cone 10 R with body reduction and a 5 min oxidation at the end.
What clay did you use? John Weber

this sounds like a good testing of the glaze, i hope that more of you will
test out the glazes that I have been posting and report back on the results.

If no errors were made in mixing the glaze, i.e omitting an ingredient,
adding too much or too little of something, etc.,your floating blue may have
been brown because the glaze was applied too thinly.
Chuns need pretty good reduction to develop rich color. The claybody can also
greatly affect the colors of chun glazes. I fire my chuns with my shinos and
celadons in pretty good reduction throughout most of the firing past 1550
degrees. Optimally, I try to alternate 45 minuteperiods of medium and strong
reduction for greater brilliance in the glazes.
Regards,
June

Wish I knew why, John, but I'm an ignoramus when it comes to glaze
analysis and development... just follow other more clever potter's
directions. I've since examined a larger bowl from a different part of
the kiln in this firing and it's the same.... soft grayblue with some
swirly light cream to tan and sky blue in a couple of places. The clay
was (I think) Coleman's porcelain from Aardvark on the big bowl. I think
the smaller test bowl was just a white stoneware. I'll have another
firing this week and will glaze a few more in the floating blue, and
will pay more attention to the clay I use (as you may have surmised, I
use many different clays ....whatever strikes my fancy at the time of
ordering ... all ^10, however) It's not my favorite glaze, but only
because I like lots of texture (for now) and less subtle effects. There
are no pinholes etc. Big bowl looks good. It did appear that the creamy
to tan areas developed some even after being removed from the kiln ....
I don't know if that info helps or not.
