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 {ital T}{r arrow}{ital T}{sub {ital c}}{sup +} (the confinement temperature) confined or glueball matter may be able to grow as a layer along this interface. QCD is said to obey {ital perfect} {ital wetting} if these layers are planar, or {ital imperfect} {ital wetting} if they are shaped like lenses. Evidence for perfect wetting in quenched QCD is studied from a calculation of the surface tension {alpha}{sub {ital p},}{ital p}/{ital T}{sup 3} between two high-temperature plasma phases at {ital T}{sub {ital c}} on a 16{sup 2}{times}32{times}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.
