Shino?? - Sea Salt added to Glazes or Clay
Must be the company name :)
As you can see my anti virus/anti spam program
didn't block your post, just tacked a heading on it.
I add salt to my "shino" to increase the Na content.
Soda feldspar 72.5
High alumina kaolin 14
Add lots of PVA glue or heaps of CMC gum, high speed
stir the glaze & dip the pots in the froth.
I also spray sea salt solution on just glazed pots to alter
the local environment. My flambe glaze drifts
from blue/red to red/blue where the area sprayed
shifts from high K to high Na. The reason for sea salt, cooking salt
& table salt have flour or starch added to make them
free running, this settles out & clags the spray gun.
There have been no obvious overfluxing of our clay bodies
(nice flashing tho') & as we use make & use vitreous
porcellaneous stoneware changes should have been apparent.
