Dust-to-metal mass ratio (DTM) as a function of time for the fiducial G10LG galaxy. The DTM is further decomposed into the carbonaceous (’C’ in blue) and silicate (’Sil’ in red) grains, and into small 5 nm (’S’ in dotted) and large 0.1 μm (’L’ in dashed). The DTM is close to the canonical value of 0.4 in the Milky Way, where the bulk of the mass is composed of large silicate grains.
