Medieval iberian plate

Hand engraving not machine. It's very easy to detecte hand from machine engraved.

 

I believe the traditional technique of engraving such script would be by using a triangular metal graver/chisel, propelled by a hammer (as opposed to a burin pushed by hand, which would leave a smooth line). It would leave a series of triangular marks, as seen on @abdel's plate. A skilled artisan would be able to do it quickly and consistently.

 

Would this technique still have been in use in 1865?

 

The technique is still used today in many countries as it has been for centuries.... Hand chased

 

Not much help in dating, is it?

 

An experienced hammer and chisel engraver can cut just as smooth as any hand push engraver.

I’ve asked my machinist club for opinions on the engraving, since we here seem to have different opinions of it.

 

This illustrates a different tool and technique, more chasing/punching than engraving. Chasing depresses the metal with a blunt tool, while engraving removes metal.

 

I am having trouble finding a good closeup illustration of the traditional technique, but Sam Alfano's site on gun engraving describes a way to use a modern engraving machine to replicate "the hammer & chisel look for a restoration project, or [if you] just like the classic look of the tiny chisel steps". I am not suggesting that abdel's was done with a modern machine, just trying to prove that the appearance of little chisel steps is consistent with traditional hand work.

Well a member of the machinists club says his uncle engraved guns by hand and got results similar to what’s on the bowl, so that’s all I know.

I might add that whatever we come up with here isn’t going to help Abdel much. He’s got a crude bowl or plate with questionable engraving on it, and apparently no provenance. He intends to sell it. He should proceed. The worst that could happen is that he makes claims about it that are discovered by buyer to be untrue, and he’s forced to refund seller’s money. I don’t think any reputable auction house would accept it, just because they don’t like low-value items, whether or not they seem authentic.

 

I have contacted with a spacialist of a metal engraved and said me it's an old hand engraved and still used today....
