Persian Copper and Cambodian Silver

[HistoryTeacher]

A couple of my favorite garage sale finds over the past couple of weeks: I got a copper chalice from a Persian who said it was from Persia. It has a great patina on it, but does anyone know how to get verdi gris off without removing the patina? It is 8" tall and weighs 1 pound and 7 ounces. A similar one is listed with another piece here. I also got a silver bowl from someone who said it was "real silver" that she got in Cambodia. I didn't recognize the marks and knew nothing about Cambodian silver, but she only wanted $5 for it so I took the gamble. It acid tests as silver and weighs 172 grams. The mark seems to suggest it is 90% silver, but I can't read the rest of the marks. Here is a short article on Cambodian silver. The only sizeable silver pieces I have gotten recently have been unusual international pieces.

Lovely pieces! What time frame/era would something like that be? Thanks.

The Cambodian silver is probably fairly modern. Probably a cheaper piece made for the tourist market. Some Cambodian silver is quite elaborate. I don't know about the copper Persian piece. The patina is quite deep and rich like an old penny. I haven't been able to find much about Persian copper work. I did get that one from a Persian immigrant, but he didn't give me much history about it. At least I can be fairly sure it is not a tourist piece.

Nice find on some chased repousse metal work. Hopefully Red-Coat will come along and explain the marks.

Yes, as History Teacher noted--and restated here by another....."T90 is a modern mark used in Cambodia. If you go there, you will found items with this mark easily and the price is low. They are handmade, but most people think they are silverplated on cupronickel."

What are your concerns with the other piece? It looks really great just the way it is actually.
Maybe a picture of the area showing the verdigris.
@Tom_Restorer is the master of restoration and he can direct you on any concerns.
Here is his person page, top notch work and knowledge.

Hi Folks, I thought to open this thread and show the process step by step because it is in my opinion a rare complete find in nearly perfect condition. The piece has all original ropes, resin or bitumen on it and the fuse is covert with canvas. A question to the specialists here: Was this...

Thanks for the tip about Tom. The spots aren't large, but I do have other old copper pieces I would like to restore without removing the patina.

I have an old recipe to remove verdigris. 1 part baking soda, 1 part washing soda, and 1 part distilled water. I’ve never tried it and have no idea if it works or what it would do to the patina.
