This is an old metal bowl signed on the bottom Jos.Heinrichs, Paris +New York, SILVER SOLDERED, NEW PALM BEACH, see in the pic I took of the bottom, It measures 4 1/2 " across at top 3 3/4" across at bottom and is 3 1/4 " high. It is in good condition,no dents.Very well made, has hammered on the outside and is smooth on the inside, and how much it is worth, any thing you could tell me on it will help me.

Thank you.

Joseph Heinrich
New York, NY
Paris, France

Joseph Heinrich began his own business c. 1897 (until c.1925).
He produced items of copper with silver accents for most of the major retailers. Most of his work would only bear the retailer's marks. Silver soldered means silver plate.

It sounds like an interesting piece. Please post the photos or e-mail them to me and I will post them.

Scott, It is my understanding that the term silver solder or silver soldered stands for the method the parts of the piece are bonded together, to differentiate from the technique of bonding with lower temp solder such as a lead or tin alloy. Technically the use of a silver alloy to bond two pieces together is called brazing. The term solder is supposed to be used for the lower melting alloys. Just a bit of trivia from a silversmith... The items I have seen by Mr. Jos.Heinrichs have always been very plain and utilitarian, usually with a well hammered surface and often silver plated if it is to be used for cooking.

I must admit the term Silver Soldered has always bothered me. Every time I have had the opportunity to personally inspect items marked Silver Soldered they have always been (without question) silverplate. I once thought (as you described) the term Silver Soldered may have had something to do with bonding, particularly when there have been mounts or assembly. But I have also seen this mark used on Silverplate where there aren't mounts or assembly. Most often I have seen this mark on Tiffany silverplate. In my book ("The Guide"), I avoided including this term in my Glossary because I couldn't locate any supporting documentation.

Does anyone have any documentation that could clear up the historical use of this term?

I can't add much on "Silver Soldered", but I can add a little about Heinrichs. Not much is really known about the firm, other than the fact that they were one of the most prominent copper manufacturers of the time, selling through outlets like Tiffany's. Some of their work was quite spectacular and artistic, but the bulk seems to have been high-quality utilitarian wares, like kettles, pots & pans. I had never seen any Heinrichs silver plate until your post.

Looking at your piece, I think it is a piece of Hotel Plate. I would bet that "NEW PALM BEACH" is/was the name of a posh Florida hotel.

As for marks, Heinrichs pieces can be confusing. Their best artistic wares were often unmarked, or marked only "Silver-On- Copper". I recall seeing some pieces marked "Sterling-On-Copper", which might also have been theirs. Interestingly, the marks seem to have been used indiscrimiately. I once saw a nice fully marked Heinrichs copper samovar on stand with an alcohol burner. As part of the mark it read "Silver on Copper", even though there was no silver on it at all!

My impression has always been that the terms "Hard Soldered" and "Silver Soldered" were to give the impression that such soldering gave a stronger bond than soft metal solders like lead and tin. As far as I know, they do (if done properly). Questions for FredZ: is my impression correct? Does the term "brazing" connote the use of a brass or brass type alloy?

My own probably unhelpful contribution would be that this seems to appear almost exclusively on silverplate destined for commercial use. (Which is what much of Tiffany's plated output was destined for.) Very little in my experience was meant for home use. The closest explanation I have ever come across is that the item was made from silver solder itself. The solder does contain some silver, and is hard enough to be made into utilitarian items. When plated, there was enough underlying silver color to mask wear.

This was designed to work with the commercial polishers. This was a box filled with tiny glass beads. The beads in turn were agitated into a whirlwind by a suction fan. The resulting storm cleaned the silver and left a gleam, but not a high polish. The solder content could be polished this way.

A silverplater told me this long ago. He was elderly 35 years ago, had a small shop in the Loop. And had one of these machines on hand. He showed me how it worked and mentioned this in passing.

It has stuck with me ever since. And I do recall seeing new, hand made Indian silver work made from silver solder.

Not much help I am afraid. It might pay off to research the commercial offerings of the silver makers. Wallace also used this term for a long time.

Here's a nice Heinrichs bowl that is about eleven inches from handle to handle and roughly three and three-eighths tall. It strikes me as being of superb quality. The mark is interesting. The only bronze on this bowl as far as I can tell is part of the handles.
