In a first step of a comprehensive study of the macroscopic and microscopic properties and structure of osmium, solid samples were successfully levitated, melted, deeply undercooled and re-solidified under vacuum. Using non-contact diagnostic methods, several properties of equilibrium and non-equilibrium liquid osmium were measured. Over the 2670-3380 K temperature range, the density could be expressed as ρ (T)=1.91x10^4-1.16 (T-T_m) kg・m^<-3>, where T_m is the melting temperature (T_m=3306 K). Similarly, the surface tension and the viscosity measurement data could be fitted respectively as γ (T) = 2.48x10^3-0.34 (T-T_m) mN・m^<-1> and η(T) = 0.00167 exp[2.2x10^5/(RT)] mPa・s over the 3230-3605 K temperature interval.
