Reply to Comment on Pseudopartial Wetting and Precursor Film Growth in Immiscible Metal Systems
In “Pseudopartial Wetting and Precursor Film Growth in Immiscible Metal Systems”, we state that droplets of Pb on Cu, which we observe in equilibrium with a monolayer film of Pb, are an example of “pseudopartial” wetting. The strict definition of the term, at least that given by Brochard-Wyart, et al.,1 requires that the film thickness arises from a competition between short- and * To whom correspondence should be addressed. † Department of Materials Science and Engineering. ‡ Department of Physics. § Center for Complex Fluids Engineering.

long-range forces. In our case, the monolayer thickness of the observed film likely arises strictly from short-range forces. We recognize that Bertrand et al. have seen a system showing a film thickness arising from the competition between short- and long-range forces, as described in ref 1. (See for example ref 2.)
