Designs such as this one are created by layering a mix of different colored opaque and transparent glass stripes onto a clear glass panel. The upper image is an iron oxide transfer combined with colored glass powder. The double layered panel is melted together in a kiln and may require multiple firings at different temperatures. Color intensity changes as the sunlight filters through it.
