Abstract: The effect of chromatic polarization observed in samples prepared for studying thermal conductivity of weak solid solutions ($p$-H$_2$)$_{1-x}$Ar$_x$ has been described. Bulk cylindrical samples have been grown in a molybdenum glass ampule through desublimation followed by control of their quality in polarized light. In contrast to weak solid solutions ($p$-H$_2$)$_{1-x}$Ne$_x$ with a heavy quasi-isotopic neon impurity, the samples with argon at the same concentrations (several parts per million) exhibit inclined chromatic bands due to elastic mechanical stresses induced after cooling to liquid-helium temperature.
