First of all, for the old glazed dragonfly eyes, they are glazed materials, and glazed glass is a borosilicate glass with low hardness. Long-term wearing or frequent wiping may cause tiny scratches or abrasion on the glass surface, thus affecting the gloss.
In addition, the color of the old glazed dragonfly eyes is colored by metal ions in the glaze. Although the technology is exquisite, metal ions may undergo chemical reactions when exposed to sunlight or chemicals for a long time, resulting in color fading or becoming less bright.
Therefore, in order to ensure the beauty and brightness of the eyes of the old glazed dragonfly, it is recommended that the wearer:
1. Avoid prolonged exposure to strong sunlight;
2. No direct contact with chemicals;
3. Try to avoid collision with hard objects to avoid scratching the glass surface.
Generally speaking, if properly maintained and used, the old glazed dragonfly eyes can maintain a certain beauty and brightness. However, because everyone wears different clothes and maintenance habits, there is no guarantee that they will become more and more beautiful.
