Black and Blue

And another "discovery" from the Glazing Techniques Class.  Alan Perlof (California) found this combination.  Val's Satin Balck with Nuka sprayed on the cup which was upside down.  We all thought it would run but to our surprise!! Best cup ever!

Michael,

Thank you for the Nuka and all your postings!

Michael, it also looks good over Oribe, getting a nice blue with a purple mottling.

Nuka may be my new favorite glaze. I may try it over a copper red next time.....
