(a) Schematic diagram of the furnace used for the in situ experiments. (b) Temperature profile within the furnace measured for three different nominal temperature settings of 750, 850, and 900 °C. The melting point of BaBrCl at the start of the experiment is located within the temperature gradient and moves up when the control temperature is reduced.
