Abstract
THIS study was undertaken to explore the feasibility of measuring infra-red emission spectra of bulk, opaque minerals. As this involved the examination of the rough, irregular surfaces of bulk specimens at temperatures close to room temperature, emission methods using conventional spectrometers1 were not applicable. The emittance of specimens near room temperature is too low to operate dispersion spectrometers.
