In the quenched approximation of QCD, the high-temperature phase (or gluon plasma phase) will be found in one of three degenerate vacua characterized by the average value of the Polyakov loop. Such vacua can coexist separated by a sharp interface. As T-->T+c (the confinement temperature) confined or glueball matter may be able to grow as a layer along this interface. QCD is said to obey perfect wetting if these layers are planar, or imperfect wetting if they are shaped like lenses. Evidence for perfect wetting in quenched QCD is studied from a calculation of the surface tension αp,p/T3 between two high-temperature plasma phases at Tc on a 162×32×4 lattice. By comparison with the value of the surface tension of a hadron-plasma interface, the data suggest that planar slabs or at least very long lenses develop along the interface, implying that QCD obeys perfect wetting.
