The utility model discloses a single piece fireproof glass. The glass forms a rounded structure at four corners of the side surface, and forms a chamfered structure on the peripheral edge portions of the front and back sides, and the chamfered portion forms a curved surface when the corners intersect. The curved surface intersects the rounded corners to form a good corner closure structure, which makes the single-piece fireproof glass have a strong anti-cracking function.
