We investigate the universality of the microbranching instability, by comparison between the characteristics of a mode I dynamic crack, in both poly(methyl methacrylate) (PMMA) and soda-lime glass. We demonstrate the existence of the instability in glass, and the similarities of its features in both PMMA and glass. In glass, as in PMMA, there is a well defined threshold for the appearance of microbranches. This threshold is higher in glass 0.44.
