Abstract : The silicate glasses are vitreous oxides which are relatively inert chemically. The high-silicate glasses are attacked only very slowly by water and salt solutions. They have the attributes of high compression strength and low density. A study was made to determine what effect, if any, extended periods of stress and strain during exposure to the chemical and biological environments of the ocean had on the structural properties of surface-compression strengthened (SCS) glasses. Exposures for as long as 504 days, while under constant strain up to 60% of ultimate, and the growth and subsequent removal of marine organisms did not deform the specimens and increased the bending strengths of the SCS glasses.
