Question on hammered copper bowl

I found this bowl a few years ago and getting ready to part with it.

I'm not that familiar with the high end copper bowls and what the market is like. I'm not saying this qualifies in that area. I did wipe it down a bit so the patina on the inside doesn't represent anything easily removable by a damp cloth.

This one does look old, not sure if as old as early 20th Century Arts and Crafts period.

It's 8 inches wide by 3 inches high. It has a little bit of damage as far as rim not perfectly circular. I'm not sure if this is common or a sign of it being very damaged.

 

It looks like it was used to hold a potted houseplant.

 

Yes, it does. Plebeians!

 

I wonder if there is some way to restore the patina on the interior, like lighter fluid, etc.

 

Six inches. My guess 1960 or so Mexico

 

Thanks. It could be. It looks like mine once had one of those L shaped inserts. What was their purpose?

 

Dissolve the calcium/mineral deposits with vinegar,etc.

 

matches...it's an ashtray..

 

Could also be a hobbyist piece. Condition of the interior makes this virtually worthless. Can be cleaned to bare metal with hydrochloric acid but would need to re-patinate to restore value.

 

Thanks. I know that vinegar and salt can make an extremely powerful and extremely dangerous hydrochloric acid, but it could do the job with the proper mask (the big kind with the disposable filters). Maybe a lesser strength would work. Definitely needs to be done outside.

 

Don't do it, it takes many years to get the patina. I have seen many nice pieces ruined because someone decided to make it pretty. Original Dirk Van Erp lamp went from $60,000 to $1000. Just sayin!

 

Yes, very true.

I would not know how to put back a fake patina also. Might be online.
