Help cleaning 1820s badge

Hello

I recently picked up this rare badge from ebay. It belonged to a Thames waterman who would ferry passengers on the river thames in London. The badges were worn on the sleeve of a jacket and issued from 1803-1827. I am currently researching who it belonged to.

I am told it is Silver on copper and have been gently cleaning it with silvo and a rag today. The surface letters and things have come up lovely but notice there are lots of dark areas that silvo polish wont seem to bring up.

Is it possible to get it back to original looking or is it corroded in those areas hence the dark colour? Obviously i do not want to do any damage but wanted to clean to how it looked when new

Cool badge, like a taxi driver or bus conductor would wear :wink:

Thank you

Any ideas on cleaning?

Honestly, I like the contrast between the darkened areas and the areas you can easily reach with the polish. You can remove all the darkening, but the shine of the metal in these areas will be a little less.

You will boil water, take a container, put a piece of aluminum foil, your item and a little baking soda (half a teaspoon for this item) in it and add the hot water.

Leave it until the water cools and then wash it with a toothbrush and mild soap. I believe you will have to repeat the process one or two more times if the darkening is very intense.

Lovely piece. Please leave the black, it gives depth. Over polishing ruins antiques and some items. Since it is silver on copper I would not use the aluminum foil baking soda method, I have ruined plate pieces doing that (A chinoiserie tea pot). A gentle polish with a jewelers cloth is a good way to bring out the shine. If you feel you must bring up the silver shine a mild mild polish with a good silver polish like Wright’s, Goddards or Weiman will buff up nicely. Dont let the cream or paste dry in the crevices. A very soft tooth brush helps with mild rubbing in the crevices. Polish buff rinse and repeat go SLOW. If you want it to look new then be very slow in the polishing once you ruin the plate the copper shows thru and replating in not only expensive but ruins in most collectors eyes the item. No insult meant bright is nice.

I disagree with you on one point, when you polish, you are mechanically removing metal from the piece, when using aluminum foil with bicarbonate, you will only react with the silver that is oxidized.

2Ag₂S(s) + 2Al(s) + 2Na⁺(aq) + 2OH⁻(aq) → 4Ag(s) + Al₂O₃(s) + 2Na₂S(aq) + H₂O(l)

The problem with the baking soda and aluminum foil method is that it leaves microscopic pits on the surface of the piece. These tiny pits then become new sites for oxidation, so you end up chasing your own tail.

I appreciate your point of view. From bitter experience I did that process with an American made silver plate coffee pot that was very precious to me. Now I might have done it wrong, I’ll give you that. It ruined the pot. I would not risk that method with silver plate or sterling again. Should one want to use that method I would first practice with a piece of silver plate that I didn’t give a rats patootie about. Once sure of the method in the users hands then risk the badge. H2OMan’s badge IMHO is too rare to mess up by chemical polishing, not Tarnex or any dip sold for jewelry. I clean allot of sterling, the liquids especially and the dips produce a tinny or harsh silver tone IMHO. Whereas hand rubbing with a jewelers cloth or polish and a soft rag brings out a lovely luster. Been burned don’t want a mess again. APCMETAL perhaps you could post a video teaching how to use the aluminum foil and baking soda successfully. I would like to see how. Thanks for your insight

It looks like most of the silver plate has worn off on all the high spots. The baking soda method might be the only way to really get into the crevices and reveal the plate in the low spots, but I don’t know what that would do to the exposed brass. Or you could go at it carefully with a well worn bristle toothbrush and a good cream polish and then rinse well in water with a bit of dish soap. But me? I"d just leave it as it is. I think it’s beautiful.

I completely agree with you, only baking soda would be able to remove all the darkening and having the contrast of the polished parts with the darkening is more beautiful. It has happened to me that I put sterling or 800 items in baking soda and realized that the darkening that I wanted to remove so much gave a special touch to the piece, I think I would say it even made it more alive. There are times when we have to experience, to value something that we did not notice or value before.

A recommendation that I just remembered, avoid mixing different items when cleaning with baking soda and aluminum foil. It happened that I put 3 items in and only one was darker and then the 2 that were cleaner came out dirty.

Try not to think of it as dirt rather as patina and, like the surface on 18th century mahogany created by generations of housemaids and their polishing kits, leave it well alone.

The badge is of great interest to those curious about the Thames which as almost everybody interested in London, or Londinium as the Roman named it.

The absence of bridges, the opposition to them being built, both as navigation hazards and for aesthetic reasons, made the role of the waterman or wherryman vital.

A quick look at the remnants of the original Roman bridge — considerably inland from today’s river banks reminds us that the city was an estuary town built in marshland stretching for miles.

The first stone London Bridge – the one with all those houses and stores piled on it was built on caissons making the water between them run so fast and at certain tide times drop so fast and so far, dozens of waterman died every years just getting between its arches.

Here’s HV Morton writing in 1939: “The Thames… Everything begins and ends with that river whose ebb and flood is the pulse of London. I saw its waters below me, dark, oily and swift, and I began to think of its nineteen centuries of history, a long time for men to have lived in the same place […]. To each generation, the Thames, coming freshly from the sea and returning again to the sea, might be said to symbolise life itself.”

Shortly after he wrote this, most of the docklands were destroyed by the blitz and the waterfront of the busiest port on the 19th century world disappeared.

My own London forebears were intimately involved in the river and the men that worked on it both as wherrymen and dockers.

A piece of silver I would love to see, but never will, is about the size of your disk. It’s the small .925 plate that was put into the skull of a river man by my maternal GG uncle who performed the first brain surgery anybody managed to survive at St Barts.

Thanks so much. I believe that part of what goes wrong is the actual measuring and proportions.
