Hi guys,
All of a sudden I am having problems with some Duncan glazes resisting in spots and am wondering if anyone else has had this dilemma or knows what to do about it. I do raku-fired hand-built work -- use Sonora White clay body by Aardvark (cone 10 clay) -- bisque to cone 04 -- electric fire glazes on to cone 06, then raku fire for finishing.
I don't know if the problem has to do with the clay or the glaze. Just fired a bunch of pieces and found lovely resisted spots where the glaze didn't "stick". Just in spots in certain areas. Major bummer -- pieces are on order and time is short.
Any suggestions, solutions or reasons for that happening will be much appreciated.
thanks,
Karen in Gualala

The rest of the group can give you're the technical reasons. However, an
occurrence in my past comes to mind. What pattern is the crawl? When we
discovered the skin on our hands were going to pot (ho, ho, ho), my partner
and I started to slather our hands with hand cream every chance we got. We
produced some lovely (but unsellable) pots with finger-tip-sized crawl
spots. Those of you looking for a good resist product might investigate the
properties of hand cream.

Hi Karen,
Try glazing with surgical gloves on,maybe hand lotion, facial oil, or
something similar is the cause. I was always taught that skin oil wouls
resist glaze, good luck, Mike Gordon
