Comparisons between measured extinction on small particle systems and the same quantity derived from scattering calculations using bulk optical constants often show substantial disagreements. Based on such comparisons, certain pitfalls which have been recognized in such a process, as it applies to the modelling of interstellar dust properties, are pointed out. Illustrations are taken from laboratory work on SiC, graphitic carbon, and olivine-type silicates.
