Step by step instructions


  1. Put the gloves on.
  2. Prepare a copper piece that you want to apply the pattern. The protective layer is best rests on slightly uneven surface, so treat the item with a metal wire.

  • Seal all except the surface with which you will work, masking tape (usually the patterns etched on the flat parts, so you need to seal the back side). If you are concerned for her safety and want to be safe before sealing, apply a thin layer of protective mixture.

  • Now you need to apply the pattern to the copper. Protective pour the mixture into a jar, dip a brush or a pen-the pen into the mixture and draw of copper of the desired image. As a rule, whatever you take, it will be thicker than ink, so if you chose a pen-feather, be prepared for it. Keep at hand a solvent – if something goes wrong, remove with dampened cotton wool in it superfluous line.



  • Pour the chloride in a plastic tub and put the item inside, side of the pattern down.

    Etching continues from half an hour to 4 hours, depending on how deep you want to make patterns. To test this, stick to the back of the long strip of masking tape before you plunge it into the chloride, and from time to time remove.

  • After etching, thoroughly rinse the item with cold water, and then wipe with a swab dipped in solvent, removing the protective layer.
