Process to create the three samples consisting of either single larger subsamples of the ceramic disks, smaller grains that were kept separated, or smaller grains that were mixed together. For the samples with the grains, ceramic disks were crushed in a mortar, and the particles were rounded and smoothed using the procedure described by Nasir et al.41. Black = alumina material. White = air.
