Removing baked enamel from coin
Hello fellow collectors,
I have a nice quarter eagle that has the Indian painted and glossed over with a baked enamel surface. Is there any effective way to easily remove this without *too much* damage to the coin? The coin, in my opinion, is already damaged due to the extra "artwork", but I would like to get it back to the look of just gold without scraping the metal surfaces. Has anyone ever encountered this or have any suggestions? Thanks in advance... |

most enameled coins are pre engraved to get a depth of colour, if you remove
it i think you find the coin pretty dire. "Wes Chormicle" wrote in message et... Acetone? "spamnot" wrote in message ink.net...

I seriously doubt you can get it off the coin without damaging the
coin. My suggestion is that you put it in a bezel and give it to your wife or girlfriend (but not both!). TD |

If it is "real" enamel, which is kiln-fired glass, laquer thinner won't work. To remove real enamel, one would have to suspend the coin vertically and fire in a kiln until the enamel ran off the coin. But, I doubt the OP has access to a kiln to do this. That said, it could be the same kind of coloring you experienced, colored epoxy resin. This COULD be removed by soaking in laquer thinner. Jonathan_ATC |

(A.: the glass doesn't have to "melt" as such - it "fuses" and/or "softens". Copper only has to be red-hot for this to happen to the enamel.) Irrelevant to the question at hand, though. Reheating would *not* cause the glass to "drip" off, though heating then rapid quenching in water could well crack it off nicely. -- Jeff R. |

What is the melting point of 90/10 Au/Ag alloy? How does that compare to kiln firing temperatures? That said, it could be the same kind of coloring you experienced, colored epoxy resin.

That's how I get all the enamel off projects that get screwed up. I heat the piece with torch and quench it. The enamel "pops" off nicely. However, one had better have safety glasses on as it really pops. I've never tried reheating it in the kiln, but figured that would work too. Why would it not work? Jonathan_ATC |
