Crystal medals are a symbol of nobility, purity, and prestige, often used in awards presented by governments and businesses. They are suitable for qualification certification, award presentation, and commemorative use at important events. The production process involves the following steps: material cutting, pressing, rough polishing, fine polishing, drilling, carving, sandblasting, gluing, quality inspection, and packaging. Crystal trophies can be crafted using techniques such as Donghai crystal carving, a national intangible cultural heritage. Counterfeit and substandard products made of glass to imitate crystal exist on the market; such actions may constitute the crime of producing and selling counterfeit and substandard products.
Maintaining crystal medals is actually quite simple. Just dilute ordinary cleaning solution with water, place the medal in the solution, and wash it with a soft brush or by hand. Then rinse it thoroughly with clean water and let it air dry. When it is semi-dry, wipe it clean with a soft towel, leaving no watermarks or fingerprints. Avoid using alkaline, acidic, or alcohol-based cleaning agents, as these can corrode the product. Additionally, trophies and other similar items should be kept away from heat to prevent oxidation and yellowing. Do not wait until the water dries before wiping, as this will leave watermarks. Therefore, wipe it when it is half-dry.
