Ancient glass, as rare archaeological findings in sites, which clarifying the skill and technology of artisans in controlling the furnace heat and know-how about the raw-mix in glass industry. Due to the glass destruction in burial setting, ancient glass has different defects depending on its application and the way of use. Destruction and damages in historic glass happen through the effects of environmental factors on surface of the glass or through mass transfer due to changing the conditions

Non-destructive methods in identifying the structural nature of the objects and the destruction during ages have higher priority than other techniques. In this article some historic glass discovered from the city Istakhr belongs to the early years of Islamic are evaluated. To analyze destructive structures Light Microscope with reflected light and Electron Microscope were used. These methods help to identify and analyze surface destruction such as weathering corrosion and iridescence in order to have a better understanding of corrosion structure and types of damages.
