INSTRUCTION

  • PLAN OUT HOW YOU WANT TO USE YOUR ETCHED METAL (jewelry applications: ring, pendant, bolo tie, bracelet; objects: box, label; etc.)
  • CUT YOUR METAL (use copper, brass, or aluminum)
  • SAND & CLEAN ONE SIDE (use 1000 or higher grit sandpaper, clean with water, ammonia, or alcohol)
  • APPLY THE IMAGE (you can use a sharpie to draw your image, or you can transfer toner onto the metal using heat or acetone)
  • ACID FLOAT (use clear tape to attach your metal image side out to a piece of foam)
  • ACID BATH (put the metal side down so that it floats in the acid - leave for 45 mins for a light etch or 2+ hours for a heavy etch)
  • BAKING SODA BATH (neutralize the acid in a baking soda bath for 2 mins - then wash with water)
  • HEAT & PICKLE (you can remove the sharpie or toner by heating the metal with a torch and then pickling to remove fire scale)
  • USE YOUR ETCHED METAL IN A PROJECT
