We infer an interstellar dust extinction map with an average $A_{\\text{V}}$=1.08$\\pm$0.38 mag, consistent with a small contribution (<22%) to the Crab's overall infrared emission. The Crab's supernova dust mass is estimated to be between 0.032 and 0.049 M$_{\\odot}$ (for amorphous carbon grains) with an average dust temperature $T_{\\text{dust}}$=41$\\pm$3K, corresponding to a dust condensation efficiency of 8-12%.
