Relationships between the applied main-ram load and the generated pressure for MA 6–6 cell assemblies in the Hyaku-shiki press. Solid squares and diamonds represent pressures generated using second-stage anvils with TEL 3 (at 1120–1470 K) and TEL 7 (at 1150 K), respectively. Pressures were determined by the equation of state of olivine. Compression curves were determined from a series of pressure-calibration runs in the MADONNA press. Dot-dashed curve: TEL 7 and the cubic pressure medium with an edge length (CEL) of 11 mm at room temperature. Solid curve: TEL 3/CEL 5 at room temperature. Dashed curve: TEL 3/CEL 5 at 1120–1570 K. The black symbols represent the pressures generated in the MADONNA press. Crosses: pressures determined by the equation of state of olivine (note that the efficiency of pressure generation was improved because the olivine sample was sandwiched by two hard-alumina pistons). Circles and triangles: determined by the phase assemblages in the recovered samples. The starting material was powders of quartz, Fe₂SiO₄ fayalite, (Mg_1.8,Fe_0.2)SiO₄ olivine or (Mg_0.9,Fe_0.1)SiO₃ ortho-enstatite. Qz: quartz; Coe: coesite; Fa: fayalite; Ahr: ahrensite; Ol: olivine; Wad: wadsleyite; Rin: ringwoodite; En: ortho-enstatite; Aki: akimotoite.
