My first exposure to the concept of bottle walls was through one of Mike Reynold’s earthship books. Mike developed the idea of earthships in the 70’s when recycling was in it’s infancy. Landfills were filling up with glass bottles–a foolish waste of an amazing material. What Mike found was that you could build walls of amazing beauty and durability, that evoke the feeling of stained glass, by using these discarded (dare I say, “disgraced”?) receptacles.
