What's wrong with some Jianjian glowing at night
The cause of this problem may be the composition, temperature and other reasons.
1, glaze composition: the glaze of Jianjian usually contains metal oxides, such as iron and copper. These metal oxides will produce radioluminescence phenomenon under high temperature, which makes Jianjian emit bright light such as blue light or gold light at night.
2. Firing temperature: Jianjian is usually fired at a high temperature of over 1300℃. This high temperature makes the particles in the body of Jianjian activated, generating electrons that release energy during the energy level jump, forming the luminescence phenomenon.
