A wood‐free resin pencil comprised of a lead made of graphite particles dispersed in a polymeric matrix is proposed as a convenient low‐cost electrode for the ‘Voltammetry of Microparticles’ technique instead of paraffin impregnated graphite rods. The pencil electrode was successfully applied for the characterization of insulating (Prussian blue, zeolites) and conductive (silver selenide, pyrite) microparticles in various media. The voltammetric responses were comparable to, sometimes even better than, those obtained with applying other electrochemical techniques.
