How to Age Pewter Images

Pewter is a brilliant metal consisting mostly of tin. Because it is generally malleable and flexible, it can be fashioned into a wide range of wares including goblets, dishes and utensils. New pewter tends to possess a shiny lustre, and this quality is what attracts so many to it for decorative purposes.

However, aged pewter can attain a gorgeous oxidised outer later called a "patina" that gives it a truly antiquated look -- here is now to attain it without waiting for years on end.

Put on your rubber gloves and safety goggles before handling any of the mentioned chemicals.

Pour half a litre of cool distilled water into a large mixing bowl.

Add ammonium chloride, copper acetate and vinegar to the bowl one at a time. Pour slowly and carefully.

Measure the pH of the mixture in the bowl with a pH strip. Take note of this measurement.

Slowly pour a small amount of nitric acid into the mixture, stirring as you do so. Measure the pH intermittently until the mixture has a pH measurement of 1 (very acidic).

Submerge your piece of pewter into the bowl, ensuring that all parts are coated with the liquid. Alternatively, the mixture can be applied with a paintbrush or sponge.

Place the pewter piece on a towel in a well-ventilated area to air-dry.
