I just realized that I didn't ever post on how we aged our zinc table top (see the topping a table with zinc post here)
In this photo the new zinc is on the right. It looks similar to stainless steel. The piece on the left is after several coats of cupric sulfate solution.
The cool thing about the zinc is that this isn't permanent. You can take 320 or 400 grit sandpaper to it and go all the way back to the shiny, original finish.
The cupric sulfate is a blue color and it is a chemical. You mix this with water. The more water the less of a patina you get, but if you put it on straight with no water it turns almost black.
This is the top of another table we did with one coat of solution brushed on. You can rub it on with towel as well....
We let it sit overnight and then wipe it down with a wet towel.
You can also roll it on with a paint roller or cover your table surface with saran wrap which puts some interesting texture in the patina....
This is several coats of patina applied over several days.

These are some edge pieces that ran down the edges of the table base....
If you just put your zinc on something and do nothing to it; it will age on it's own over time. The company we buy our supplies from sells wax similar to butcher's wax and we use that to seal it up. If your piece is going to get alot of heavy use the wax will eventually wear off, and then the patina will start to wear off as well. If you notice that it seems to be wearing off you can reapply the wax. Anything acidic can take both the wax and patina off completely and it will be shiny again.
