    I would suggest this is a very bad idea.

    What a strange question. Silver, even in very small doses, is a poison to humans and other life on Earth.

    Of course, metallic silver on the surface of serving dishes isn't exactly a new concept. I don't know why a person would ask this question, exactly, but I don't see that it's vacuous: Is the metallic silver in a print more subject to being transferred than the metallic silver in a silver fork or teapot?

    I would suggest that a silver coating on paper is a bit different to a solid silver cutlery or electroplating.

    Yes, and aside of any toxicity of fine dispersed metallic silver: with that dish you got water and heat, both detrimental to gelatin surfaces in first instance.

    I don't know of such. Typically you nowadays got plastic foils aluminized by vapour deposition or paper on which a ultra-thin alumium foil has been laminated.

    An ancient recipe from an archaeologist , if you serve wine in silver coated paper , no headache at the morning. Thats why British and Americans may be others made tankards out of silver.

    I can't imagine someone can make disposable plates at price point those things sell and still manage to use real silver. Assuming this is the case, then a real question is, what is the silvery stuff that's on the plate OP is talking about.

    Also, "plastic" is such a generic term. People have been talking about plastic plates and containers being harmful for many years, yet so few references to exactly what plastic they are talking about....

    Too bad---I thought he wanted to coat emulsion on dinner plates and print on them. Which I suppose could be an interesting idea, in its way, though I have no idea how safe it would be.

    Perfectly safe when followed by a stout chaser of ammonium thiosufate. That should fix everything.

    If you are referring to the medical condition called argyria the presence of silver in the body poses no health rise. This condition is evidenced by the skin turning blue in color. So people with this condition look very strange. Silver and most of its compounds are only slightly toxic to humans. Silver has strong antibacterial properties. For decades newborns had a small amount of silver nitrate solution instilled into their eyes to prevent any venereal disease of the mother from causing blindness in the infant. Recent research has indicated that very small amounts of silver vastly increase the efficiency of many antibiotics. This may solve the problem of antibiotic resistant microbes.

    Is it a guy? He/she posted the same question twice within a minute at 7:30pm but the second post appears to have been removed. It was clear that a number of APUGers weren't clear as to what he/she was referring. His/her last activity I noted was almost 8:00pm and yet he/she didn't attempt to clarify his question which, given he/she has just joined seemed a strange introduction to APUG.

    I suppose the same question twice might have just been a mistake. Pity that his/her nom de plume is "nag" which might just be a coincidence as well. However if he/she is serious about his/her intentions in joining a photographic forum I do hope he/she will try and clarify what he/she means by silver coated paper plates and what prompted this as his/her first post rather than a more pertinent one.

    Call me cynical but I cannot help feeling we may have been "taken for a ride" just to see what reactions the question creates. Isn't this the kind of thing psychology students do to investigate "subjects'" reactions

    Gerald, we have to distinguish between silver-salts, plain metallic silver and metallic silver of the nano-scale. And in addition the different types of exposition. Things can get complicated by this.

    Pentaxuser, I have no problem being taken for a ride in case that ride trickles my thinking. Not quite sure about that in this case though.

    Studies have confirmed that silver and its compounds are not particularly toxic. I cite the following monograph by the EPA.

    http://www.epa.gov/IRIS/subst/0099.htm

    In actuality iron and it's compounds are more dangerous. As little as 20 mg per kg can cause serious poisoning. Iron poisoning is endemic in certain portions of Africa where the people subsist on a corn meal porridge cooked in iron pots.

    Charley, I am so sorry to hear this news.

    I am certain OP is concerned about plates that are commonly available at department stores in the Birthday aisle, which I am quite certain contain no metallic silver.

    I have hosted some holiday celebrations, notably the 4th of July (AKA Independence Day in the US). The plates were metallic silver, blue and red. And the guests who I served grilled chicken to have not turned blue.

    I am confident that (despite lack of FDA oversight of production) these plates are safe to serve human food upon.

    As Bill Burk, I've seen paper and plastic plates with "silver" patterns in the "party shelves" of stores. I'd assume that the printed patterns are not real silver and are obviously food-safe. But there are always warnings on paper and most plastic utensils not to use them on heat or in a microwave. (Obviously. :whistling: )

    TBH, I'm not sure about the original question or why it's asked here. Surely the packaging or a phone call to the manufacturer would provide more useful information.

    Real food should be served on real plates.

    trying to coat silver-based emulsions onto paper plates so they could be used as paper plates sounds like the ne-plus-ultra in post-post-modern conceptual/performance art, made to make a statement about disposable consumer culture.

    There's nothing in the OP's post that makes any photo connection and no sign of the OP. Troll or random weirdness.
