I received a question from a long-time customer that I honestly do not know the answer to! "I am now looking at coffee pots but I wonder: Since they are very old and probably have silver loss inside from the acid in the coffee how do you clean the inside and especially the narrow spout? Is it possible to replate the inside of the spout?" I know that there must be silver experts here who can easily "spout" this answer. Thanks in advance, and an early "Happy Holidays" to all!

Hello Abesilverman! If you use the all forums search function on this forum for cleaning coffee stains you will have your answer... I think. Jersey IP: Logged |

I don't think silver desolves in coffee acid. Rather it looks to leave a film of brown crud which actually acts to protect the silver. Yes, when immeresed in the cyanide bath, all surfaces inside and out are covered with silver. Including inside the spout. IP: Logged |

Thanks, Dale. That's what I thought, but I wasn't 100% certain. Certainly not enough to advise. If I may, one more question. IP: Logged |

It depends on what metal is used as the substrate combined with the sensitivity of an individual to that metal. There was no Consumer Product Safety Commission or such until fairly recently and so there was no real concern or control over what went into the alloys that were used as the base for silver plated objects. Also, toxicity is a complicated thing where sensitivity to exposure to substances varies where young and old people, or malnurished people or hypersensitive people experience problems at lower levels of exposure than healthier adults typically do. It also depends on length of exposure over time. If the base metal is pure copper with no traces of other elements, for example, the maximum allowable concentration in drinking water permitted by most health departments is 170 parts per billion. Above this level and you can get some people beginning to show signs of copper poisoning which in such low doses is normally not too bad and can be symptoms such as stomach pain or nausea and headaches. In the most extreme cases that have been documented in some parts of the world such as India where it was found young children's milk and water were routinely stored and served in copper vessels, there have been a handful of deaths recorded. On the other hand, a person needs micro trace amounts of copper in their diet to be healthy and you sometimes see it as an ingredient in multi-vitamins. If you want to use an old plated tea or coffee pot that has its plating inside wearing through and you want to use it regularly you should do one of two things - either leave the build-up of tea or coffee residue that coats the inside and let it act as a barrier, or get it replated with a good thick plating.

(A bit off topic perhaps, but) regarding the traditional use of copper pots to store water: the recent introduction of plastic water storage containers in rural India had an unintended side effect -- increased instance of water-borne disease. Copper ions, in the low levels found from storing water in copper jars, turns out to be an effective antiseptic! And (very off topic), clothing manufactures are now embedding copper and silver ions into clothing for the same reason. I believe I read somewhere on these forums that Queen Elizabeth used silver service because of it's LOW likelihood of causing an unhealthy reaction. But as the post above indicates, in higher concentrations, and especially other heavy metals such as lead, would be of greater concern. IP: Logged |
