Time evolution of the carbon dust mass. We gathered data from Li et al. (2022), Maeda et al. (2013) (SN IIn: 2010jl), and Stritzinger et al. (2012) (SNe IIn: 2005ip and 2006jd). The symbols are different for different spectral types of SNe; IIn (circles), IIn/Ia-CSM (diamonds), 2005ip and 2006jd (squares), and 2020uem (star). The open symbols show the upper limits of dust mass, while the filled symbols show confirmed dust mass.
