eng	Surface tension in chalcogenide undercooled melts and melts studied by surface structure flattening and drop analysis	The prepared contribution shows data on surface tension in amorphous Se-based chalcogenides. The chosen materials are studied in the melt region, close to the melting point, and in the undercooled melt, close to the glass-transition temperature. In the region of melt, the surface tension is calculated using the program OriTas analyzing the profile of a hanging droplet. Near the glass-transition temperature, the surface tension is evaluated from the rate of flattening of a surface profile embossed into the studied material. Combining the data obtained near glass-transition temperature and above the melting point can provide a tool to interpolate surface tension data in the undercooled melt that are important for the description of other processes taking place in the studied glass-forming materials.	surface tension; chalcogenide; undercooled melt
