The following is the recipe for the glaze you requested:
=20
=20
Blue Hare's Fur ^ 6 Oxidation
=20
Nepheline Syenite 47.30
Gerstley Borate 27.00
Silica 20.30
EPK Kaolin 5.40
=20
Add:
Red Iron Oxide 2.00
Cobalt Oxide 1.00
Rutile 4.00
Bentonite 2.00
=20
I believe I got this recipe from Clayart or Clay Times. I do not know =
to whom to attribute this glaze.
=20
This is one of the class glazes I've used for the last several years =
with good results. It is a nice gloss texture. It also has a mottled =
visual texture, hence, the name. It's blue where thick and dark brown =
black where thin. On occasions the color develops more towards blue =
green instead of blue.
=20
I fire in a Bailey top loading electric. The ramp is 150 degrees F an =
hour to 900 F, 150 degrees F an hour to 1830 F, Hold at that temp for 60 =
minutes, 150 degrees an hour to 2232 F, cool down naturally.
=20
I do want to try the firing down protocol that Ron and John advocate. =
I'm not sure if it will have any effect on this glaze.
=20
Good luck!

Rafael - I use a similar Blue Hare's Fur glaze that I have
substituted frit #3134 for the gerstley borate and increased the
amount of EPK for better glaze suspension, of course I had to alter
other chemicals. I have noted the cooling down cycle does have a
great influence on this glaze. A faster cool down results in a bluer
color, while a slower cooling rate causes the glaze to be greener.

Please also note that the colour of this glaze is very much determined
by the clay body. In testing various forms of this glaze recipe I used
6 different types of clay test tiles, and they were all very different.
The tiles were fired on the same shelf, and in the same kiln. From
there I repeated the tests in another kiln, and got different results
again. Nice glaze, when it works, but too variable if you want any sort
of consistency.
