The extent to which silicate grains in a circumstellar dust shell can account for observed infra-red emission from two supernovae is investigated. The two supernovae used in the modelling are SN1979c and SN1980k both of which are known to show a variable infra-red excess. The amorphous silicate used in the modelling is a composite silicate. Predictions are made regarding the spectral features which should be present if this type of silicate exists in such dust shells. It is concluded that the amorphous silicate used in the modelling may not be entirely appropriate to that which exists in the dust shells of the Type II supernovae discussed. The usefulness of this type of modelling in providing estimates of masses and sizes of such circumstellar dust shells is also examined.
