- 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 ~1600°C and then rapidly quenched in air.
