He cut a small detail section (the base) from approximately 1800 bottles collected and placed them in a cement mixer containing sand and water. This slightly modified the appearance of the plastic by creating a sandblasted quality which made the plastic appear like frosted glass.
What great use of the plastic bottle that would have simply ended up in the landfills! Besides, this chandelier is so beautiful, a great coversation piece!
Hope you are having a wonderful and creative week!
