The temperature difference will cause the inner layer to expand far greater than the outer part. When you pour a very hot liquid into a thick tumbler what happens is the surface of glass that comes in the contact with the hot liquid heats up and expands as per its coefficient of thermal expansion while the outer layer is cold and does not expands. 2 Stresses in solids move only as fast as the speed of sound.
