This new product has been developed by a British company over the last 2 years and its combination and mixture of materials used to make them and their creation are totally unique, so it is necessary to protect its manufacturing process in the near future. However we can say that they are not glass, but do invlove the inclusion of crystal minerals. The combination of total ingredients have never been manufactured before. They are twice as strong as glass and many times more expensive. No dyes, colours or pigments are used to create the effects seen within the spheres and in fact use nanotechnology to produce their colours, which change as the sphere is turned. Each sphere has it’s own unique interior structure and is about the size of a cricket ball.
