Silver tea service set -- metal questions
"Ignoramus11713" wrote in message ... Today, I bought the following tea service set at a garage sale: http://igor.chudov.com/tmp/silver_service I paid $25 for it. The seller told me that it was made of solid sterling silver, bt I did not believe him (and hence got my price instead of asking price). I bought it purely because it was looked good and I assumed it was made from some cheap metal that was silver plated. Upon getting home however, I tried to make some deep scratches in an unconspicuous place in one piece, and to my surprise, despite making a deep scratch, the metal beneath was still relatively soft and silvery looking. The stamp on the service pieces refers to some silversmith. The set weight about 7 lbs 6 oz, according to my postal scale. I have no intention of selling the set as it would look great in our house. I have two questions: 1. How can I check if it is really silver 2. How can I clean the dark silver safely and effectively. Thanks Your simple test may or may not tell you anything. Often the base metal under silver plate is the same color as silver, so when the silver wears away you can't really tell. Sterling silver is an alloy commonly used for such things, along with silver plate. It would be highly unlikely your items are made of pure silver. Sterling is a composition of 92.5% silver, 7.5% copper. Scandinavian countries used different alloys of silver and copper, some as low as 70% silver. The marks on your pieces should tell you what they are made of. Look for a number like 925, which would be sterling, 900, which would be "coin" silver, Also look for hallmarks, such as a lion. Tell us what you see marked on the bottom of your pieces and we may be able to tell you what you bought. If you are interested in a non-destructive test for silver, there is a solution that will react blood red when applied to silver, a mixture of distilled water, nitric acid and potassium dichromate. Nitric acid alone will also react, leaving a cream colored surface on the item being tested if it is silver, but a green reaction if you test a scratch through a plated item. None of this is difficult, but if you haven't seen the tests done before you may not understand what you are seeing when doing the tests. If you can provide more information I may be able to tell you more. .. Harold |

Tarn-X Gary Thanks, I just cleaned it using the electrolytic method, details at same site http://igor.chudov.com/tmp/silver_service i Whatever you do, don't use tarn-x. It destroys the value of real silver, if by any chance that was what you actually bought. Sterling acquires a patina by being rubbed with normal silver cleaner over many years, it's a pain in the ass to do but it's the only thing that will really preserve the value of good silver. If it's plate it's far less important, as most plate has very little monetary value, and the silver is gradually removed with polish. For what it's worth, unless it's marked sterling the odds are incredibly high it's plate. Are there any marks at all? |

Sterling acquires a patina by being rubbed with normal silver cleaner over many years, it's a pain in the ass to do but it's the only thing that will really preserve the value of good silver. Thanks Richard. We cleaned it in boiling water with soda and salt and aluminum foil, and then a little with baking soda. If it's plate it's far less important, as most plate has very little monetary value, and the silver is gradually removed with polish. obviously the plate has very little value, yes, but it looks very beautiful. So plate or not, we will keep the service. I did however do some tests whether it is solid sterling silver. I scratched the tray with a key, making fairly deep scratches, in an unconspicuous place. Two things became apparent, that the metal underneath is relatively soft, and second, that it is silvery. I have a set of tiny brass cups that are silver plated, those are obviously plated as there is yellow metal beneath. In my current instance however, there is no such yellow metal and also it is too soft to be steel of any kind (incl stainless). Plus the sellers said that it was solid sterling silver, which I did not believe originally, but now it is starting to be more believable. For what it's worth, unless it's marked sterling the odds are incredibly high it's plate. Are there any marks at all? It refers to some silversmith. I did not see any marks saying it is sterling silver, but I will look again. i First, there are lots of base metals they put electroplate over, so merely not seeing copper when you scratch it is no big deal. The base metals are often soft. You sometimes see electroplate over German Silver, which isn't really silver at all, it's a soft, easily cast alloy with a silvery color. Can you post a link to a photo of the mark? If it says E.P. followed by anything it's electroplate. The same thing with quadruple plate or Sheffield plate. If it was made in the US, it would pretty much either say Sterling, or if it's fairly old it might say CS or coin silver. The name of a silver company doesn't mean it's silver, many companies sold both sterling and plate. |

Solid sterling silver is marked as such and plated is also marked as such.
There are very rigid standards for marking such materials and violations are often harshly dealt with to the manufacturers. That doesn't mean that somebody can't mark the parts with the wrong marks but they first have to get rid of the proper marks. I'd do a google to see what the proper marks are as well as the manufacturer that made the set. -- Bob May Losing weight is easy! If you ever want to lose weight, eat and drink less.

snip At least I paid $25 for the set, and it looks great after cleaning. I figure that it is worth at least $25. And By The Way, I did not believe the sellers when I was buying. I started believing them after I did some testing. i If you like it, that's all that really matters. Retail value is meaningless if you like something and intend to keep it. How well something would sell only comes into play if you bought it to resell it. I buy lots of stuff that I could never resell for what I paid for it. I buy it because I like it, what someone else would pay for it is irrelevant. |

I have some Rogers plate, that was my mothers. If it doesn't say "sterling"
on it, it's plate. Some times Sterling will have a decimalised purity number instead. Steve Rayner. "mrbonaparte" wrote in message news:rkcXa.34514$Ne.20859@fed1read03...

I generally sell stuff on ebay, mostly military surplus. I do not plan to sell this service on ebay because I like it, but I am curious as to how much it can fetch. http://igor.chudov.com/tmp/silver_service I looked on eBay, and the vast majority of Rogers sets sold for around $25-30. As for the the $300 in an antique shop estimate, when I had booths in antique malls in the Dallas, Texas area, Rogers teapots and coffee pots generally went for around $20 or so in antique malls, and could be bought at auction for under $10 each. The set you've got wouldn't bring more than $75 in most shops in my area, and generally wouldn't be found at all except in antique malls and fairly low end shops, as modern plate doesn't sell particularly well. They're common as dirt, because damn near everyone got one as a wedding present, and no one ever used them. That being said, it really doesn't matter. You bought it because you liked it, you couldn't buy it new for anywhere near what you paid for it, and after paying shipping fees you couldn't buy it on eBay for what you paid for it. Forget about what it's worth, and enjoy it. |

They're common as dirt, because damn near everyone got one as a wedding present, and no one ever used them. First, condition means a lot. Buying sight unseen on ebay leads to reduced value I repair antique metalwork for a living. I charge $20 to remove a simple dent in a silver plate pot, The dealers bring me 2-3 a week. Second, sets bring a premium. Orphan pots are bought by college students and young marrieds, trying to decorate. Sets are bought by someone who is looking for a 25th anniv gift for their cousin Leon. Here's a generic set, sans tray for $175 http://www.kassai.com/items/145156/i...tore.html#item Here's a more collectable set, with tray for $1095 down in DFW http://antiquesbytrudymiller.com/eteryours_teaset.htm Back in the Bunker-Hunt days, we trashed tons of this stuff. That being said, it really doesn't matter. You bought it because you liked it, you couldn't buy it new for anywhere near what you paid for it, and after paying shipping fees you couldn't buy it on eBay for what you paid for it. Forget about what it's worth, and enjoy it. This, I fully agree with. A silver teapot is one of the worlds most useless things. You will spend more time cleaning it than using it, but it is an attractive thing, that you would never have thought about buying retail. You paid as much as you would have for a movie and popcorn. If you only pull it out on thanksgiving, you will have had more enjoyment than it's cost . Paul K. Dickman |

The traditional tea and coffee service is five pieces: tea pot, coffee pot, creamer, sugar and tray. Yes, we know that. I can't tell from the picture if the items here pattern match. The tray isn't right, and neither are the pieces. I've got some infusers I've never listed. Maybe I should list one for him to buy. Better yet. Trade him a teapot for one of his extra coffee servers.

You may, but the owner can't find the silver marks, let alone necessarily know what the trad set is. I just thought I'd mention it. I can't tell from the picture if the items here pattern match. The tray isn't right, and neither are the pieces. Tray's too small for a set. Most sets used a rectangular tray for the sets, but not all. I've got some infusers I've never listed. Maybe I should list one for him to buy. Better yet. Trade him a teapot for one of his extra coffee servers. Nah. He can put boiling water in one of the coffee pots and dangle a silver-plate tea infuser in a cup. Much classier than a tea bag. Then, I've got a couple of tea strainers - the kind that fit over cup - to put the soggy tea in. Think he can be taught to bend his pinky? If he's got any money left, I have some nice sterling sugar cube tongs. Why is it, by the way, that most restaurants will give you unlimited refills of coffee, but charge you for a second little pot of hot water for tea? Will you be mother? |

This is a case where the item is so low-end, what you see is what you get. We disagree on what is "low-end". Real low-end is a china teapot made by someone in one of those paint-and-fire-it-yourself shops that is hand-painted with flowers that look like mutant posies that grew in Hiroshima in the late 1940s, a music box in the base that plays "Tea For Two", a wobbly bottom, and a spout like a leaker hose. That, and a creamer that is shaped like a cow vomiting half-and-half and a sugar bowl in the form of a bull's scrotum. Put them on a metal tray with a lithograph of Elvis in a white suit with sequins, and you have "low-end". A silver-plate service is sophisticated compared to this, provided that you have a white living room suite with clear plastic slip-covers and a huge Capi de Monte lamp with a fringed shade on a recoco lamp table in the picture window. You can sit and watch the silver-plate grow tarnish. It's like watching a lava lamp. |
