I recently purchased two beautiful antique sterling serving pieces; however, it appears that the previous owner dipped them and removed all the beautiful blackened oxidation that brings out the details. Is there a "quick fix" that can be done to duplicate the effects of time? IP: Logged |

It takes experience to get a lasting effect but you might want to try using Liver of Sulfur. IP: Logged |

There is a quick and easy solution. Jewelry supply stores sell a bottled solution for darkening silver. Dip the piece for seconds to minutes, no more. Rinse. The entire piece will be darkened. Now polish or lightly buff the superficial areas leaving the deeper areas darkened. We have often used this on pieces that were dipped in anti-tarnish solution. IP: Logged |

Bob and Carol--do you have a product name for that dip? I have been trying to find such a product for some pieces in my collection that were dipped in anti-tarnish solutions. There are no jewelry supply stores in my area but I might be able to purchase it online somewhere if I know the brand/product name. IP: Logged |

We dip in "silver/black" made by "Grobet USA" Label states "for a smooth black patina on silver, gold, copper and bronze." We bought one 4 oz bottle and have used it repeatedly. IP: Logged |

I recommend brushing on the blackening solution rather than dipping it. You have more control and you can localize the areas you wish to have darkened. It is also safer to use on hollow handles if it is brushed on. Dipping hollow handles runs the risk of introducing this liquid into the handle. The color tends to be very black and not as subtle as that gotten with Liver of Sulfur (Sulfurated Potash). Depending on the condition of the decoration, I sometimes will use a FFF or FFFF grade of pumice to remove the color from the high spots and then polish with a silver polish. The pumice is usually available or can be ordered by your local paint distributor. Slaked plaster can also be used as a mild abrasive. Fred IP: Logged |
