Each are made from exactly the same stuff. Each were made in exactly the same way. Each were made in exactly the same place.
And each look very very different.
A patina is the color meatal takes when exposed to the elements. Have you ever seen the green sculpture out in front of the art museum in SF?
It didn't start green, it is made of bronze, and bronze or copper turns green. Cars are made of steel, and when exposed they turn brown.
Or rust color LOL
So if these four bars of ours are all the same material why do they look so different?
Even in the same environment they have had different lives. Some are older, some have been used more, some have been beaten up more, some have been treated or cared for differently than the others.
Artist will artificially speed up the process of putting a patina onto a sculpture, because the patina adds to the sculpture. A patina shows off the sculpture. A patina gives the sculpture character. Gives it individuality.
I have all the tools to make it happen.
