The invention relates to a frame for supporting a glass plate during a quenching of the glass plate. This frame includes a supporting ring for supporting thereon the glass plate, and a heat-resistant fabric tensioned and covering a top surface of the supporting ring to allow the glass plate to rest on the heat-resistant woven fabric. The supporting ring has a shape substantially conforming to a contour of the glass plate. A quenching air of the tempering is allowed to pass smoothly by tensioning the heat-resistant fabric.
