anvil, ring

(no subject)

Sigh. Now my bottle of Cuprinol is failing to spray about 70% of the time. I am re-thinking the mouth-driven thingy that can apply a thin coat of whatever that is reportedly used by ceramicists; one of the things holding me back is that I have NO idea what it's called. Any ceramicists reading this that can give me a name, or a better description than that above? I would be most grateful!

I am quite impressed by Cuprinol as a firecoat, and would like to keep using it. I'd also like to use some of the HUGE amount of Pripp's I made up! There's another firecoat I have that I haven't tried yet- Ceramcoat or something? I may try that tomorrow, or the next time I kiln anneal gold.

I used some scrap palladium (it's H&S's 950 alloy, for them what care), rolled it out pretty thin, and will be testing 4 solders on it for color matching. I stamped the strip 1-4, then made wee roundish depressions next to each number for the different solders. I'll be testing (all from H&S) Pd hard, Pd medium, 18k palladium white gold hard, and 20k white gold hard, and we shall see what we shall see about color matching. I'm under a tight deadline for some Pd rings, so I'd best get this done tomorrow, while the rings are annealing before being formed for soldering!
