A study of the high‐alkali region of glass formation in the system Na2O +B2O3 reveals that retention of CO2 from carbonate starting materials can become a serious preparative problem at the high‐alkali extreme. Results presented for glasses prepared using both Na2O and Na2CO3 show that residual CO2 can lead to major differences in physical properties which in this work are represented by the viscosity‐related glass transition temperature.
