My next door neighbor is building a tree house and he wanted some junk insulators to put on the roof of the tree house. He asked me if I had any in my back yard. So I looked around and picked a few. I noticed a chandelier of insulators that I bought a few years back. I noticed some purple tint on one of them. There were 12 insulators on the chandelier. I cleaned it up and placed in my lye bucket. And this what it looks like. It does have a busted air bubble on the base but what a find! I will add another picture. This will be for sale in Denver.
