Some metals (copper, brass, silver) darken in the air. A clear protective layer slows the process.

![Steps of the technique: Clean and polish, Degrease, Apply, Dry, Second coat, Check](https://www.711grados.com/media/diagrams/lacado-steps.en.svg "Summary of the steps")

## Types

- **Clear lacquers** (for example for copper and brass): create a hard film.
- **Microcrystalline waxes:** a thin, renewable layer.
- **Costume-jewelry varnishes:** a temporary barrier against sweat.

## How to apply

Clean and degrease the piece, apply a thin, even coat and let it dry or cure as the maker instructs.

## Limitations

Lacquer wears with rubbing and can yellow. On a piece worn daily, a plated coating lasts longer.

## Compatibility

Do not apply it over pearls or porous stones.

## Step by step

1. **Clean and polish.** The metal must be bright.
2. **Degrease.** With alcohol.
3. **Apply.** A thin, even coat.
4. **Dry.** Or cure as the maker says.
5. **Second coat.** If needed.
6. **Check.** No bubbles or drips.

## Tools and materials

- Clear lacquer or microcrystalline wax
- Brush or spray
- Alcohol
- Gloves and ventilation

## Common mistakes

- Thick coat: it drips and yellows.
- Applying over dirty metal.
- Touching before it dries.
- Using it on pearls or porous stones.
