An investigation has been made of the possibility that polarizable ions in the surface of glass might retard the hydrolytic stress corrosion considered responsible for the gradual loss of strength of glass fibers under stress (static fatigue). Techniques were developed for simul taneous testing of large groups of glass fibers in bending. Fatigue tests covering the loss of strength over seven decades of log time were carried out. Fibers drawn from a specially prepared glass in which the highly polarizable Pb ++ ion was substituted for Ca++ and Mg++ in "E" glass were compared with "E" glass control fibers. The Pb-containing glass showed no significant improvement in fatigue properties.
