The
story of the Sapphire Blue
A
few months ago I mixed a glaze by the promising name Sapphire Blue. I was surprised
to find out that the glaze came out of the kiln actually green. I thought I probably
made a mistake while
mixing the glaze, by omitting the Cobalt Carbonate while
talking on the phone or something.

I tried to mix the original one again, this time in a very small amount, and it
did came out a beautiful sapphire Blue.
Very happy, I made a
whole new bucket of the first glaze, and changed the name to Sapphire Green.
This time it
came out pale orange.
Therefore,
I have mixed 3 more litters of the glaze, repeating very carefully the original
recipe; the Sapphire Blue. If I can't
get the Blue again, at least I'll have a beautiful green, but no, not me…
Yesterday I've started a Glazing day, this time with taking photos of every piece after every
step, so I can track what I did, when the dishes come out of the kiln.
What a shame
when I looked over the photos I have
found out that I used the old bucket with the wrong glaze again… the one that came out orange…
mean time, I have already glazed 6 pieces.
and also two large vases

I did put some spots of the "right" glaze on top. Now I am waiting to see what a surprise will come out of the kiln this time...

A glaze that can turn three different colors, how wonderful, but not when they don't turn out as you want them to.
I am not sure if it is a miracle glaze, or it is my own lack of concentration ...
I really sympathise..too often i leave bowls of glaze or slip lying around and quickly forget what I've put in them. And then there was my lavender glaze which worked great as a small sample, so I mixed up an enormous batch of it..but the results have been disappointing & nothing like the test.
Varda Sharon Kramer,
I believe I have tested and mixed the exact same glaze you are discussing in this blog. I too got blue in the small test but green in the 10-lb batch i mixed. I lovee the green and want to mix more but the subsequent mixes all turned out horrible and react as if they are not properly fluxed and/or stabalized. were you able to get the glaze to function in either the blue or green and if so what was the key?
Thanks for visiting my blog.. I did get the Sapphire Blue as great glaze colored blue,but never actually got that beautiful green again...
