Hi Ron,
I tested several more of your recipes this week and
everything beautiful except the waxwing, I don't know what I did wrong.
Wherever the piece faced the elements and also at the waxline, it looks like
burnt sugar. I use a controlled kiln and witness cones. Cone 6 just touching.
I would say pieces between two to three inches from the elements. Although
where glaze is thinnest it also looks bubbled. Bubbles did not form craters,
but flattened and then hardened.Some bubbles as large as a dime. Soaked at
peak temp for 20 mins., then slow cooled from 1900 to 1500 @ a rate of 150
per hour. Bisqued to cone 04.
My ingredients are relatively new except for the titanium......it
might be 30 years old. I plan on making another test batch to see if I made
an error in my measurments.
TIA to all who respond.

Hi Cabdi,
If the other glazes are using the same materials as the wax wing - then you
can assume it is not a bad material - you may want to take a good look at
any that are not common to the wax wing.
It sounds to me like you have made an error in weighing or material as we
have many remarks from potters who have had success with the wax wing.
Please let us know if the repeat is not right and we will try to help solve
the problem.

Hi Candi,
Waxwing is a sensitive glaze. It will bubble like you have described
when it is fired too hot and/or when it is applied too thick. With your
particular ingredients you may need to fire it a little cooler--sounds
like you already have it on thin enough. There also seem to be some body
interactions with that glaze on occasion. Your particular body just may
not be compatible with it.
Regards,
John

I must throw my $.02 on this one; I've had the exact
same results. All of my tests have turned out the
same -- very flat, burned looking, big bubbled
craters. Most all of the other glazes I've tried from
the book have turned out pretty close to the photos.

Just for the record, my waxwing turned out exactly the same as in the book!
I used a ^6 porcelain with a reasonably thick application. Has the same
undertones and breakes the same as in the book. I think application might
be the key here as there are so many subtleties to this glaze. ........M

I tested it on two different clays in the same firing. The light brown
stoneware (Buffalo Wallow) came out fine. The other, a white stoneware
(Cinco Blanco), came out blistered and looked overfired.

Hi Kristin,
Thanks for responding - how many clay bodies do you use - any info you can
include on them would be helpful.

Hi Ron -
I tested this glaze on a ^6 porcelain from Great Lakes
Clay as well as on their light ^6 stoneware ("Domestic
Porcelain" and "Buff"). The glaze came out the same
on both. It's hard to see the flatness, burntness,
but you can sort of see the bubbles here:
http://www.tamarac.net/alby/test_tubes/010208.jpg.
I'd be happy to send you both the tubes if you'd like.
I am not much concerned with this; I'm having fun
coming up with my own brownish colors. But I just
thought I'd back up Candi, who also got my results.
When I test glazes, I do a single dip, for about 5
seconds, and then I dip the rim for an additional 2 or
so. I bisque to what I'd call an almost 04 (hotter
than 05, but not exactly perfectly an 04). In the
high fire, I hold at peak temp for 15 minutes or so,
turn it off until 1050*, then decrease at around
-80*C/hr until 800*C, at which point I turn the kiln
off, go to bed, and open the top the next morning when
it's about 200*C. The 8-10 other colors I've done from
your book in this way come pretty darn close to the
images in your book.
Thanks - Kristin
p.s. I discovered my cracking-off problem with
raspberry. I watered the glaze bucket down to a
perfect consistency, and it worked fine -- until I
double-dipped a rim. It cracked off there, so I know
now just to never double-dip with this particular
glaze.
p.p.s. While I'm providing info from my own
experiements: the clear glossy liner glaze crazes a
lot for me on the porcelain body. Long lines around
the test tubes, not short hairlines. Just looks like
they don't fit well, this glaze/body combo.
