A method for producing long-term bendable glass material includes: bending a glass material in a bending radius in a range of 1 mm to 107 mm; storing the bent glass material for a time period of at least 1 day; inspecting at least a portion of the bent glass material for damage after the storing; and classifying the inspected bent glass material as a reject if damage is detected or as a long-term bendable glass material if no damage is detected.
