The effect of mechanical stress during the drawing process on the strength obtained was determined for large‐diameter fibers of soda‐lime‐silica glass. Fibers were formed by down‐drawing cane at a constant rate, using loads of from 100 to 8000 gm. Tensile strength was determined by transverse loading on annealed specimens. The results showed that the variation of temperature and load during forming increased the strength of the drawn fiber as much as 62%. The tendency toward increased strength persisted, but to a lesser extent, after the surface of the fibers was abraded.
