Glassy carbon (GC) surfaces: 'as produced' in the carbonization process, abrased and oxidized were studied using AES, XPS and cyclic voltammetry. Evidence for the existence of an outer sheath formed during carbonization, having chemical structure and electrochemical properties different from the bulk of the GC samples has been found. Samples with outer sheath and samples where it was removed by abrasion and/or electrochemical oxidation have been modified by immersing into AgNO3 solution for about 30 days. A deposit of metallic silver has been observed on the surface of all samples.
