We propose to measure the structural relaxation in this prototype glass former. The structural ralaxation time will be obtained at the structure factor maximum. We suppose that the dynamics will change around twice the glass transition temperature. This estimate is based on our measurements on liquid metals. With this salty water we want to follow the dynamics deep into the supercooled state, which is difficult to achieve for monatomic metals.In the metals we have identified a slow structural relaxation process which is responsible for structural freezing and sets in at about 2Tg.
