Observed changes in K-paracelsian during two cycles of heating. (a) Evolution of the b axis (blue) during the temperature programme shown in orange. (b) Relative changes in unit-cell volume of K-paracelsian (blue) and the reference feldspars (yellow = albite and grey = microcline). (c) Observed sample weight during the TGA experiment (orange) plotted together with observed b axis variations (blue) from the in situ XRD experiment.
