You need to take care of your table top because is is made of natural materials and is susceptible to getting damaged with acid or abrasive substances. Below you can see some photos of a test that we did using:
- Salad dressing
- Vinegar
- Lemon juice
We left the liquids on the table top for 12 hours and the acidity of the liquids removed part or all the fired patina of the table top.
Not to worry. The contact of the clean copper and the environment ‘s humidity will cause the natural patina to surge on it’s own. It will take 30 to 60 days to gain the patina color again.
