| Abstract: | Observations of circumstellar dust clouds of Wolf-Rayet stars made with the Short Wavelength Spectrometer on ISO reveal a
subtle variety of spectral energy distributions not evident from ground-based observations. The modelling of these using the
radiative transfer code "Dusty" by Ivezić, Nenkova & Elitzur is reported. The results are used to examine the contributions
by different possible grain types to the emission and of circumstellar and interstellar components to the reddening.
