Front Surface Mirror-B is available in sheets for the hobbyist and the serious kaleidoscope maker alike. This economical aluminized mirror is used in most of Clarity’s kaleidoscope kits and refills, and is perfect for most kaleidoscope projects. Because the mirror coating is on the front surface, your kaleidoscopic images will be clear with no ghost images or blurring. FSM-B is highly reflective and comes in 6″ x 8″ sheets that are .048 inches thick and have a removable plastic lamination to protect the mirror coating. Using a carbide cutter, it can be cut into whatever sizes your kaleidoscope designs require.
