Fiber optic glass is a man-made glass composed of millions of glass fibers that have been fused into a block. This creates a reflective characteristic known as cat-eye. This material can be slabbed easily with a diamond blade. It is a great material for making cabochons as well as flint knapping into arrowheads, spears, or other shapes.
