Hi!
When there were the answers about the floating blue describing possible failure of the
glaze because of the cooling speed of the kiln, I said to myself! Yes my kiln cools
slowly too!
This is the Floating blue RR version

Good days no one knows what is cadycal, so I am not removing the GB.
I made a line blend.
I have some suggestions.
1) Try the line blend. Of course add the colorants.

Please note the first frit is 3134 (left) the second 3110 (right)
2) Try it over several colored claybodies. If you use only one kind try to paint or spray
with an engob with different amounts of red iron oxide from 4%-10% on the
greenware.
3)Try the higher alumina above this recipe:

The way I have it here is with a similar glaze is the reason why I do not try hard to float
the blue

And here.

Please note: the recipe I send here is better than the one on my site.
Here is my renewed page at Fabienne Cassman's site
