Zinc is chine and decorates your garden. By oxidizing, it forms a layer impervious to air, thanks to its patina. That’s why the architect Haussmann used it a lot during the redevelopment of Paris. It is supposed to withstand the ravages of time and bad weather.
Different from the marbled sheet
Zinc is known for its strength, lightness and strength. It is easily transformable. However, it happens that there are traces of rust. A zinc in perfect condition is very rare to find on flea markets. These objects have served a lot, but it gives them this incomparable patina precisely, it’s all their charm. But most of the zinc objects you find are not quite zinc. It is often steel coated with a layer of zinc to protect it, in short this is called galvanized steel or commonly galvanized sheet.
They may end up rusting, but it takes a long time to get there. Differentiating these two types of zinc is difficult for the naked eye, except that real zincs are rarely damaged. Galvanized sheets are a little marbled, but there is no real interest in making a difference, apart from aesthetic, because it does not change anything in the price.
If zinc is too rusty, choose a mixture of tin salts and water. Soak your object all night and finally brush the rust spots. If your room has calcareous deposits, the good white vinegar will do the trick. If the zinc is punctured, apply silicone gel found on the do-it-yourself department. It makes it easy to seal a bucket. You can also keep it pierced to put in perennials. If the zinc is blackened, like a washing machine, which spent time on the fire at the time, use caustic soda.
