Beveled glass is usually made by taking thick glass and creating an angled surface cut (bevel) around the entire periphery.Bevels act as prisms in sunlight creating an interesting color diffraction which both highlights the glass work and provides a spectrum of colors which would ordinarily be absent in clear float glass.
Beveled glass can be obtained as clusters which are arranged to create a specific design. These can vary from simple three or four piece designs, often used in top lights (commonly known as transoms) of windows and conservatories, to more complex combinations of many pieces, suitable for larger panels such as doors and side screens (known in the door industry as sidelites).
