Hi Again Ivor. I posted this here previously (found the message in the
archives just now.) Please try this glaze and you can see the bubbles for
yourself. This is a nice sky blue on grolleg, white where thick or drips.
Really likes a white body or white slip. Not so nice a blue on an iron
bearing body. Cone 10 but easily goes higher. Enjoys the same reduction I
use for shinos. I get almost all my coloration in my glazes from Iron. I
use copper a little bit. I like blues, but not cobalt blues. I am also fond
of soda ash, rutile, wood ash and bone ash for the diversity they give to
glazes. These are materials that require cooperation rather than a master.
Going to try bone ash in the nukas and kaki here. I'm thinking that bone
ash might turn the kaki more red, like Hamada's.

For purple Splash: 3% copper in slip on raw body (can make a slip from your clay
body, just sieve the grog out a little bit.)
