Contact-free thermal air bearing slumping

In slumping of glass sheets there needs to be a separation layer between glass and mandrel to keep them from fusing together. Inhomogeneities in that layer and dust trapped between glass and mandrel lead to mid-spatial frequency ripples in the shape of the glass. In this project we are avoiding this problem by using a porous air bearing as the mandrel and floating the glass sheet without any hard contact during the slumping process. See here for background.
