The Archimedean single bob technique was employed to secure density data in the range of 1350–1710°C for selected molten slag compositions in the CaO–SiO2, CaO–SiO2–MgO, CaO–SiO2–Al2O3, and CaO–SiO2–MgO–CaF2 systems. In each system, the measurements typically revealed minor to negligible density variations across the temperature range. In cases where density variations were apparent, density was observed to slightly decrease as temperature was lowered. The density variations between the different slag systems are significant, with lower densities generally associated with the more acidic (higher per cent silica) compositions.
