The formation of dust plays a key role in the mass loss from stars during their final evolutionary stages. We propose to investigate the composition of dust around AGB stars in the Globular Cluster NGC 104 using IRS. The AGB stars of our sample are well defined concerning their mass, luminosity, metallicity and variability. Our results will not only provide insight into the dust composition in a metal poor environment, but will also allow dust characteristics to be linked with the evolutionary stage along the AGB. Furthermore we will investigate the role of stellar pulsation on the dust forming and mass loss process. Finally, knowing the composition of the dust may help to understand why globular clusters appear to have so little inter-cluster dust.
