Etching -method of engraving in which lines or textures are bitten, or etched, into a metal plate, usually copper, with acid. The image produced has a spontaneity of line that comes from drawing on the plate in the same direct way as with pen or pencil on paper. The first etchings date from the early 16th century, but the basic principle had been used earlier for the decoration of armour.
What you need:
• Sewing needle
• Iodine solution
What you do:
• Light a candle and drop some wax on the knife.
• Put the knife over the candle so the wax melts smoothly and cover the area needed for etching.
• Let the wax cool down.
• Using the sewing needle “etch” the knife. Try to get all the way to the metal.
• Using the dropper drop the iodine solution on the scratches you made in wax.
• Let it sit a little.
• After the iodine solution becomes pale drop a little bit more.
• Let it sit for a couple of hours.
• Wash off the wax and you’ve got yourself an engraved knife.
Note: We ran the knife through the dishwasher and the engraving was still there.
