  • 1. ETCHING FOR ARTISTS AND HACKERS Kyle Geske SkullSpace Hack-a-Thon April 2011
  • 2. ETCHINGThe process of using corrosive chemicals to cut into theunprotected parts of an object’s surface.The process has been around for hundreds of years andhas both artistic and industrial uses.
  • 3. Mankindhas alwaysstrived toleavepermanentmarks uponthe world.
  • 4. THE ISHANGO BONEA 20,000 year old baboon fibula with a piece of quartzaffixed to one end. The bone is covered with the markings ofa tally stick. Was the quartz perhaps used for engraving?http://en.wikipedia.org/wiki/Ishango_bone
  • 5. ENGRAVINGThe practice of incising adesign on to a hard,usually flat surface, bycutting grooves into it.In ancient times coinswere manufactured usinghand-engraved dies.European goldsmiths inthe Middle Ages usedengraving to decorate andinscribe armour, weapons,jewelery, and other metalwork.
  • 6. To preserve andcatalogue theirdesigns, goldsmithswould make “prints”of their work bytaking impressionsusing cloth or paperwith charcoal andink.
  • 7. With the arrival of theprinting press inEurope in the early1400s, the engraving ofmetal plates to produceimages on paper cameinto its own.Many early engraverscame from a goldsmithingbackground.Albrecht Dürer.The Knight, Death and the Devil c. 1513
