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!
YES! THANK YOU!!!!! That looks like exactly what I need. I appreciate it so much!
Glad to be of help! I started out with the keywords 'glaze' 'blow' 'applicator', and then 'glaze' 'mouth' 'blow' 'applicator' had more useful results.
Your google-fu totally trumps mine! I tried a buch of things- I don't even know what-all- and got stuff that was, at least, not appropriate for my uses. Probably because of "blow" or something. :)
I am greatly appreciative! I think I'll order severeal, and have one per compound, though I am not precisely looking forward to developing the coordination necessary to use the things... Still, there are only so many spray applicators I can trash before I know I need an alternative.
cupronil is by far my favorite flux. i've never had a problem with the spray bottle getting blocked up though... pripp's was HORRIBLE when it came to blocking up the sprayer (though i liked it as a flux). but how odd that the cupronil is doing the same thing.
My Cuprinol sprays beautifully and consistently when I spray it into the sink to see if it's working... and then won't spray 2 times out of 3 when I actually have a warm piece I'm trying to fire coat. SO annoying! Perhaps it was a fluke, though- thanks for letting me know that this is not its normal behavior.
I'm researching ways to get the damn Pripp's to spray, since I made up a TON of the stuff, as it turned out. :P
