The glass unit is designed as a cooktop plate unit. The coating is configured to produce metallic appearance. An electronic unit (60) measures and evaluates electrical characteristics of the former layer formed by semiconducting material, and detects a safety parameter. The subregion is formed as cohesive face and a closed line. The main face is formed as a continuous kink-free face.
