Abstract: The present invention provides a method for evaluating a processing deterioration level of a medical glass container, including (a) a step of imaging a surface of a medical glass container molded from a borosilicate glass tube to obtain an image, and (b) a step of analyzing a contrast of the image. The method is particularly useful to evaluate the amount of alkali substances which are deposited on the inner side surface of a medical glass container.
