Are enamel vases collectible? Why does it glow at night?

Enamel vases are collectible and glow at night because fluorescent powder is added to the material. Enamel vases are of high collection value because they are made of enamel. Generally speaking, a key point in identifying enamel porcelain is to find out its historical background, because it has rarely been handed down and rarely circulated. Turn off the lights at night and find that the vase will glow. The material on the vase is added with fluorescent powder (commonly known as luminous powder), which is usually divided into two types: luminous powder with light energy storage and radioactive luminous powder.
