Figures 1, 2, and 3 show characteristic macrographs and SEM micrographs of fused-salt templates, paraffin templates and gelatin microparticles, obtained as previously described. In Figure 1 the tree sizes of salt templates are showed. In Figures 2 and 3, only the sizes between 100 and 355mm of characteristic samples of paraffin and gelatin are shown. It can be observed that the solid template is made of homoge-neously fused and interconnected particles. The sizes of all of them are in the range of the sieve sizes.
