• The preparation of fine powders by grinding may be accomplished by either a wet or a dry process and the differences between these have been discussed. The difference of breaking strength in different atmospheres affects the grindabilities. In this study, bending tests were carried out using a drop weight method on glass material in order to investigate the quantitative effect of water atmosphere on strength. The influence of the crack length of the glass surface on the difference of fracture probability in water and in air was also studied. As a result, it was found that the fracture probability in water was larger than that in air when the input energy in specimen was constant. Then, the difference of the fracture energy in water and in air increased with decreasing the crack length.
