Abstract
A glass, a glass forming method, and a glass forming device are provided. The glass has a first surface and a second surface opposite to the first surface, and the first surface is provided with an infrared reflective film layer. The glass forming method includes the following. Heating is performed on the glass. Bend-forming is performed on the glass. Air-quenching is performed on the glass to make both a surface compressive stress of the first surface of the glass and a surface compressive stress of the second surface of the glass greater than or equal to 30 MPa. An air pressure of an air blast applied to a side of the first surface of the glass is lower than an air pressure of an air blast applied to a side of the second surface of the glass.
