Aluminum (Al) melted droplet was undercooled with the cooling rates 2-20 K/min and the crystallization temperature T$_{C}$ ≈ 642 $^o$C was detected by the Differential Scanning Calorimetry (DSC) apparatus under non-isothermal conditions. We have numerically solved the kinetic equation of the crystal nucleation within standard model to determine the time dependent number of nuclei as a function of their size. Small clusters have a tendency to diminish and only supercritical clusters (nuclei) grow independently. Standard nucleation model enables us to determine the interfacial energy limit, when the first nuclei are formed within the system.
