- The sample was produced by mixing powders of pure oxides in a proportion that resembles the composition of a Nakhlite. The powder was then molten at 1450°C to obtain a silicate melt, which was quenched to a glass. This procedure was repeated, with the glass being powdered, re-melted at 1450°C and quenched again to obtain homogeneous glass, following the procedure described in Musu et al. (2026) and Vetere et al. (2014). The obtained glass was powdered again and brought at superliquidus temperature and subjected to slow cooling (52-60 °C per hour) starting from a temperature of ~1450°C to subliquidus/supersolids target temperature of ~1000°C. The sample stayed in the furnace for three days at the target temperature and was subsequently quenched in air.
