I was working with some colorant variations in a base glaze and by
fortuitous accident created a glaze that resembles the famous floating
blue. It looks best fired in oxidation on an irony brown clay body at
cone 6. If your glaze recipe collection won't feel complete without
this new floating blue variation, you can get it here...

Hi John,

Looks good John - not a lot of SiO2 - do you know if it's stable?

The bag I am using is around 8 years old. I usually use Custer spar
but I came up with this glaze by creating an Ian Currie grid from
Glossy Base 1 in Mastering Cone 6 Glazes, and that base glaze calls
for G-200.

The base for Floating Blue is glaze #17 on the grid.

John, thanks for the additional info. If your bag is that old, it is the

Thanks, John, for the new addition to the Floating Blue collection.
The calculated expansion appears to be significantly lower than several
other versions. Perhaps this could mean no more singing blue pots on the=3D=

shelves?

Cheers,
