Thanks for sending the Rosenrot Red through your machine. I don't use the=
system but I do intend on getting Insight glaze calculator before long. (=
Also I need to look at my papers. I think I did mean 3134? For those who =
like more information on this glaze I can tell you that prior to RR's gre=
help, I had already done 2 things.
Reduce the Tin oxide to 5% and add 1.5 to 2.5% strontium.
This gives a beefy brighter red. I noticed the extra tin started to act o=
opacification at that level. I dropped it back to 5%. I have also added a=
touch of RIO 1% it works but will go toward a ox blood color.
So now we are at.
05.00 Tin Oxide
00.35 Chromium (remember 0.35% not 35)
02.00 Strontium (remove some Calcium)
Mix well and sieve twice or blend the oxides in a blender with some of th=
base and H20 then add to the balance of glaze formulae.
Also I tested this with a small amount of cobalt 00.75% and it was a gran=
smooth color. However this was written to support REDs in oxidation.
Tests were ran on 3 bodies and fired to cone. (Full bend) ^6. White Lagun=
B-Mix and Lizella Earthenware and a clay body that we quit using recently=
lizella gave me the idea for a touch of iron since it showed some great c=
I must add that Lana Wilson was/is my inspiration for working so much on =
oxidation red at ^6.
Lana and Ron and John all have been very helpful when I started removing =
from glazes and trying to recover some of those hard to find colors.
Testing and calculating over and over is about the only way to find the f=
Please advise me if you test this glaze and your results! Maybe we can tw=
it here and there if needed? It did pass the lemon slice test for nearly =
days since I forgot I had left it on there. Dried lemon slice anyone?
