Check whether the surface of the glaze is smooth, whether the color is uniform, whether the thickness of the ceramic layer meets the requirements, and whether it is conductive – for that, instruments are needed.

What instruments are used to detect conductivity?

Yes, when high voltage is applied and a brush is used to scrub the surface of the ceramic layer, sparks and noises will occur if there are pinholes. You can look for it online.

Visual inspection, high-voltage spark testing; for specific details, refer to GB 25025 Technical Specifications for Laminated Glass Equipment
