Keywords:density, silicate melt, magma, high pressure, buoyancy test

I measured the density of sodium silicate melt under high pressures by the sink/float method. High pressure experiments were conducted using large volume presses installed at Tohoku University. Experiments were conducted up to 6 GPa, and a compression curve of the sodium disilicate melt was determined.
