Abstract: An improved optical fiber for transmitting mid-infrared wavelength laser light in surgical instruments, includes, a heavy-metal oxide component, preferably GeO.sub.2 doped with heavier cations and anions, is capable of delivering of at least three watts of laser power continuously for more than ten minutes, without failure. This glass fiber has an .alpha.(dB/m) at 2.94.mu.m of 10, preferably less, and can transmit at least 27% of the IR through a thickness of one foot.

Abstract: A method, workpiece and the product thereof for making simulated stained glass works of art includes a transparent substrate covered on one side by an opaque scratch-removable coating and on the other side by transparent-ink patterns or solid colors. Portions of the opaque coating are removed to reveal through the transparent substrate, underlying transparent-ink patterns. The partially scratched product "drawing" produces an excellent visual appearance simulative of stained glass when held up to light. The finished product can be affixed to a window for continued enjoyment.
