The previously discovered features of the temperature behaviour of four-point spatial correlators allow us to study transitions to metastable states. Similar integral characteristics simultaneously study microscopic effects (vortex formation and clustering) and the effect of these phenomena on the thermodynamics of the whole system. It is shown that spatial and temporal behaviour of correlators in supercooled liquid samples determine the signs of the glass transition in a system before its relaxation. After the liquid sample is supercooled below a certain boundary, particle motion correlations on the coordination spheres sharply increase, similar to the situation in a crystal. The study was carried out using the embedded atom method model of aluminium using the molecular dynamics method.
