Effects of electron beam irradiation on mist resistance and wetting were studied for soda lime glasses.The electron beam irradiation decreased the time to clear vision on the misted soda lime glasses. The treatment was conformed to show the mist resistance of the glass. To discuss the effect of electron beam on mist resistance, it was evaluated by using contact angle of sessile drop of water. Based on electron spin resonance (ESR) results, the effects of electron beam on the mist resistance were discussed. Electron beam irradiation broke the weakly bonded pairs and formed the dangling bonds in soda lime glasses.

An effect of dissolution treatment on the fracture resistance of transparent glass was studied. The plastic deformation energy to propagate the crack was estimated by fracture toughness using standard indentation fracture method with Vickers' hardness tester. Although the influence of dissolution on the plastic deformation energy to propagate crack was not observed, dissolution of less than 0.2×10 6 s increased the plastic deformation energy to generate the crack. The increased crack generation energy was mainly due to the stress relaxation on the tip of the crack origin, which was induced by dissolution.
