Reclaiming soldered silver
Is the solder in a fabricated silver joint likely to cause problems when
melting down silver? I've had a few cases recently where a small bead of molten stuff has danced on the surface of the hot silver just before it melts. I have also had a few cases of a small crater or contaminated bubble on the surface of the cooled silver which does not seem to be removed by my pickle. Regards -Kendall |

Any solder is going to contaminate the casted alloy with zinc and possibly other metals and ingredients. You have no way of knowing how much, because you have no way of knowing exactly how much solder gets in, and you probably don't know the precise ingredients of the solder alloy that has been used. An annealing will often make soldered areas show up. Chemicals may also work, like liver of sulpher for silver alloys. Heatless mizzi wheels are great for rough grinding work. It's usually just a matter of minutes with the flex shaft. You could also just turn the metal in to the refiner and buy new metal with the money they give you. |

Reclaiming soldered silver
Thanks mb,
I guessed as much but it's nice to have it verified. Thanks also for the other advice. Kendall "mbstevens" wrote in message ...
