A study has been made of the relationship between conditions of specimen preparation and the tensile strength of small constricted soda‐lime‐silica glass rods. The preparation and testing techniques were basically the same as those used in a previous investigation' except that the drawing loads were systematically varied. It was found that different loads under which specimens were drawn resulted in significant changes in tensile strength values. The average strength values varied from 62,800 lb. per sq. in. to 88,400 lb. per sq. in., depending on the drawing loads used. Maximum strength values were obtained with the highest loads. The limits of error of the strength values did not change appreciably with different drawing conditions. Rubbing the specimens with the fingers reduced the strength by approximately 32%.
