Table 3.10.1[link] provides information about the phases used in this work. Further details can be found in the original publication (León-Reina et al., 2016[link]). All of the mixtures were prepared by grinding the weighed phases by hand in an agate pestle and mortar for 20 min to ensure homogeneity.

3.10.2.2. Crystalline inorganic series

| top | pdf |

A constant matrix of calcite (C), gypsum (Gp) and quartz (Q) was prepared. Six samples with known increasing amounts of insoluble anhydrite (i-A) were then produced and were labelled CGpQ_xA, where x repesents the target i-A content: 0.00, 0.125, 0.25, 0.50, 1.0, 2.0 or 4.0 wt%.

3.10.2.3. Crystalline organic series

| top | pdf |

A constant matrix of glucose (G), fructose (F) and lactose (L) was prepared. Six samples with known increasing amounts of xylose (X) were then produced and labelled GFL_xX, where x represents the target X content: 0.00, 0.125, 0.25, 0.50, 1.0, 2.0 or 4.0 wt%.

3.10.2.4. Variable amorphous content series

| top | pdf |

A constant matrix of calcite (C) and zincite (Z) was prepared. Five samples with increasing contents of amorphous ground glass (Gl) were then prepared. The elemental composition of the ground glass is given in García-Maté et al. (2014)[link]. The mixtures were labelled CZQ_xGl, where x indicates 0, 2, 4, 8, 16 or 32 wt% Gl. The amorphous content was determined by adding ∼20 wt% quartz (Q) as an internal standard.
