Abstract
A shaping rail uses tungsten alloy inserts to support a glass sheet during sag bending. As the glass sheet is heated and sags to shape, tungsten alloy inserts provide support points over which the glass sheet can slide without scuffing the glass sheet surface or embedding particles in the glass sheet that can result in venting.
