Our glass art witch balls begin as clear recycled glass. As the ball of molten hot glass is formed, the ball is rolled into color glass granules to provide the design. These granules are added to color 40 to 60% of surface of the finished ball, allowing sunlight the to brighten the sphere, and the strands inside the ball to be visible. Each witch ball is handcrafted unique. No two are exact. The size is about that of a grapefruit, approximately 6" diameter. These balls are sealed, and will work well as pond floats. Let the magic of our glass artists protect your home. Muted colors of Aqua, Gold, and light Cream Brown.
