Nuka glazed Chaire with burnish gold lustre accents and porcelain lid

John;

I came across a recipe for a Nuka glaze, which I understood to be white. I was interested in it as it uses wood ash, which I have an abundance of.[dangling participle there]. I mixed up a test. Like the surface quality, but it needs to be applied thicker. On your jar, are you putting it over black slip, or is it a black clay body? Looks beautiful.

Just saw this comment Tom.  Thanks.  Very dark clay body.... Sheffield #42 with added local granite dust.

Bumping this old conversation  - ran into it googling for some info on that Sheffield 42.  How's it for coiling do you think?  I only get my clay from Sheffield,  usually Elaine's  Porcelain,  but having hit 15" of woobly porcelain coil on a fat pot this morning  I'm thinking I want something sturdier with a different character and some color the for fairly thin, soft, larger organic coiled forms I want to try.   Thinking you might have  another idea if 42's not good for that - I have a gift cert there  and would prefer ^6-10. Any thoughts? (I've long admired your beautiful work, always takes my breath away!)
