Traditional laboratory studies on dust-ice systems have proved how the nature of the dust surface significantly affects ice structure and reactivity. Although the surface composition effects have been widely studied recently, no attention has been paid to the dust sizes. We show how dust the grains size and topography, as well as their composition, affects their interaction with light and the morphology of water ice mantles on top of them.
