Unique Stained Glass Antique Insulator in Royal Purple Color Stained Decorative Glass. We create each one of these stained glass insulators in our 150-year-old converted Tobacco Barn shop. I call it the bro barn. These are authentic approximately 100-year-old clear glass insulators that we have enhanced with glass stain applied as a spray aerosol. Staining glass is a slow, painstaking process. The non-porous nature of glass requires many light coats, each one needing a considerable amount of care and drying time. Then we coat each one with a diamond clear coat, making them more scratch resistant, UV Protected and providing more shine and luster. The Royal Purple color is more of a reddish-purple color. Much more red than our violet-stained insulators but a very interesting color to shave the least. Almost a wine color. It definitely catches the sunlight beautifully as can be seen in the images. We search for insulators in perfect condition, but because they are approximately 100 years old, they will sometimes have a small imperfection or 2. These items sat up high on a pole and were subjected to rain, heat, wind electricity, birds, and other elements for many decades. Your insulator might have a small scratch or a tiny ding but it will definitely not have any easily discernable chips, cracks, or sharp edges and the staining process hides almost all imperfections.
