Transverse section macrography of the plate where the degradation by thinning is worst, close to the original corners of the tube. The thinning is occurrring from the product reaction side (side A to the bottom of the figure). The macrography shows a reduction in the thickness from 2 mm (right side, sample 2) to almost zero (left side, sample 1).
