Bent glass lamination 1 If the curve of the bent glass is small, you can laminate it by vacuum bag. Noted: The shape of the wood should match the maximum curve of the glass. 2 If the curve of the glass is big, you can use C style silicone tube. Take out the shelf of the machine, and then put the bent glass into the machine. For the C style tube, you should know the thickness of the glass, such as if your glass is 3+3mm, then the C style tube is 3+3mm. The length of the tube depends on the glass Perimeter, the tube will buckle around the glass. such as your glass is 1*2M, then the tube should be 1*2+2*2=2+6=6meters.
