Well, I used 2 of them to test some new glaze techniques. Using slip trailing and glazes, and then dipping the whole piece into a glaze bucket.
Here are the results.
My conclusion is that slip trailing is still a messy job for glaze, and it allows the 2 glazes I tried for the plates to just intrude over it onto the faces...they used to have chins. Vertical surfaces are a real no-no for this glaze technique.
On the plus side, putting a thin coat of clear over the slip trailed and glazed portions does work, no crazing which our clear glaze often gives. However I think it contributed to the blurring.
I really want highly defined black lines, within which I can use different colors of glaze.
If you have a recommendation, please leave a comment. Thanks!
