Consider two glasses. Glass A has a composition of 5% CaO - 95% B2O3. Glass B has a composition of 15% CaO - 85% B2O3. Both samples are cooled from their molten state to room temperature at rates that result in an identical glass transition temperature. Given this information, identify which melt was cooled at a higher cooling rate to achieve identical Tg.
