Time evolution of the system during isobaric heating at 250 bar. a A set of representative color scaled density maps are presented to indicate a few significant moments: when the color changes from blue to red, then the coexistence of orange reddish with yellow, and then the conversion to pale yellow; the length of the scale bar is 5 mm. b The temperature profile recorded before the monolith with the indication of the temperature of the plateau (Tpb(exp)). c Vertical densities profiles and d densities histograms for the monolith region. Each point in the temperature profile corresponds to a line in the density profile and a density histogram. Source data for b–d are provided as a Source Data file
