The present invention includes a step of cooling a molten metal within a fine space present in the inside of an object and hardening it while applying a forced external force exceeding atmospheric pressure to the molten metal. To that end, the method includes varying a transport of the gases disposed proximate to the viscous liquid. The first and second driving signals are amplified by first and second amplifiers, respectively. The operating electrolyte according to the invention is distinguished by an improved sparking voltage and permits the capacitor according to the invention to be used at voltages up to 530 V. A dispensing reservoir tip is coupled with the body.
