Abstract (excerpt)
The {\it assumption of additive absorptivity} by different components in compound particles is a widely used method applied in the literature to the analysis of the chemical and structural properties of astronomical (circumstellar, interstellar, protostellar, and cometary) silicates as well as other materials. The errors intrinsic in this additivity assumption, which, in application to astronomical spectra, amounts in some case to {\it spectrum subtraction} have not always been adequately considered in previous works on silicate mineralogy. The failings in the ``{\it spectrum subtraction metho
