We present infrared observations of 66 starburst galaxies over the full range of oxygen abundances observed in local star-forming galaxies, from 12+log(O/H)=7.1 to 8.9. ... We confirm a strong correlation of aromatic emission with metallicity, with a threshold at 12+log(O/H)~8. We show that the far-infrared color temperature of the large dust grains increases toward lower metallicity, peaking at a metallicity of 8 before turning over. ...
