Extensive observations on the strength‐fracture mirror size relation for a commercial cordierite‐based glass‐ceramic indicate a systematic deviation from the expected behavior at high strength/small mirror sizes. Calculations of internal stresses from phase properties suggest that the observations result from direct effects of internal stresses on fracture‐mirror formation or from indirect effects of internal stresses affecting the fracture toughness and hence fracture‐mirror size.
