At the beginning of the ignition region II, the current fluctuations become less pronounced (0 ms in Fig. ). Here, a large bubble expands from the electrode tip along the entire electrode, which collapses to form a vapor layer around the electrode. Concomitantly, a discharge is observed at the electrode tip (see Fig. ), which appears to travel upwards along the wire. Since the electrode is no longer in contact with the electrolyte, the current is low in this region II. In the following frames after the ignition, individual bright discharges are observed, as illustrated in Fig. . Approximately 280 ms after the ignition, continuous CGDE is observed in region III, apparent by a decrease in discharge intensity and less pronounced fluctuations in the current. These fluctuations do not change significantly for longer time scales, as shown in the SI in Fig. (constant for at least 1 min, i.e., the rest of the experiment). These small current fluctuations indicate that the electrode is completely isolated from the electrolyte by a comparably stable vapor layer. The discharges can no longer be discerned from the refraction of the background light. However, the purple emission remains evident to the eye as a continuous purple glow. The camera images recorded without background illumination (see Fig. below) clearly show that the glow results from individual discharges in this region III. We suggest that the change from high-intensity discharges that contribute significantly to the current in region II to stable lower-intensity discharges in region III is related to a change in the discharge mechanism in both regions. A more detailed study on the ignition process should be addressed in a separate work. In the following, we focus on the vapor layer thickness and discharges in region III during continuous CGDE.
