Illustration: Lacquering and surface protection

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
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.
