Fired on mid range white stoneware.
Firing ramp with an electric controller is:
100c p/h to 600c (212f - 1112f)
150c p/h to 1140c (302f - 2084f)
80c p/h to 1220c (176f - 2228f)
15 min. soak
cool down max. to 900c (1652f)
Hold 1 hour
Shut off kiln
Recipe:
7.6 Barium Carb.
18.5 G.B.
6.5 Whiting
41.3 Custer Spar
24 Silica
ADD
6.8 Copper Carb.
8.7 Zinc Oxide
86.9 Zircopax
Note: All raw materials are measured up or down to the nearest half
decimal. Colorants or additives to a 100 gram batch are measured in percent
to the 100 gram batch.
Results:
Extremely high and crawled medium to light green glaze. Glaze is thoroughly
cracked, with large lichen and crawled textures overall. A hard surface.
I would think adding almost the same weight of Zirocpax to any glaze will
produce a crawled surface. This is an expensive way to get a glaze to
crawl.
30 to 50% Zircopax or Magnesium will give many glazes this texture at cone
6.

Hello Crista:
Alisa did say in her general glaze post that she did try it and it came
out brown, She also said that she is going to try refiring.
I did try it just because the color seemed so intense but even with a slow
glaze firng it was a blah brown and even when I refired to bisque which
has wonderful results on some glazes didn't work it was still that blah
brown. But I have to confess that I used my regular red iron oxide so
maybe that is the secret.
If you try it with the mexican? red iron oxide and get red please post to
the list, thanks
Mayssan, in a very nice spring day in Charleston WV USA

----------
Mayssan and others --
I have tried the Jayne Schatz Ketchup Red with the Spanish RIO. I have
used both a fast and a programmed slow cool cycle. For me the glaze
comes out a semigloss to glossy variegated brown, but definitely not
red. It breaks nicely over texture; reminds me of the way floating blue
breaks, and even has a bit of hares fur on a smooth surface. On a small
plate, yes, it's rather plain.
Definitely not red.
I did try the Glossy Black from the same article and it produces a very
glossy, deep black and a very nice hares fur over the ketchup red --
but certainly not like the picture in CM. The Glossy Black has
manganese, however, and I use it very very sparingly.
I've posted some pictures on Shutterfly. You may have to copy and paste
the link.
