A copper free mirror is made through a chemical sedimentation process. As traditionally a sheet of specially treated silver is coated on quality float glass, followed by a sheet of special metal film instead of copper and this is then finished with two layers of paint for chemical and physical protection. Using a lead-free paint can produce a copper free and lead free high quality mirror.
The main benefit of copper free mirrors is the reduced corrosion. As above , this is the rusting that appears beneath the surface of the coating and once this appears there nothing that can be done to get rid of it. Copper free mirrors are 3 times more resistance to corrosion than traditional mirrors. Other than the benefits of longer longevity of the mirror, copper free mirrors are also better for the environment. Without the harmful chemicals such as copper sulfate and lead in the manufacturing process, the production of these mirrors are significantly less harmful to the environment.
There are also others reasons that Copper-free mirrors better than traditional copper-backed mirrors:
1. Durability and Longevity: Copper-free mirrors are more durable and long-lasting. The lack of copper backing means they are less prone to corrosion and rusting, which can damage the mirror over time.
2. Cost-Effectiveness: Copper-free mirrors are more cost-effective in the long run. They require less maintenance and have a longer lifespan, reducing the need for frequent replacements.
3. Ease of Installation and Maintenance: These mirrors are easier to install and maintain. The absence of copper backing simplifies the installation process and reduces the risk of installation errors.
4. Design Flexibility: Copper-free mirrors offer greater design flexibility. They can be customized in terms of shape, size, and color, making them suitable for various applications and decorative purposes.
5. Environmental Friendliness: Some copper-free mirrors are made from environmentally friendly materials, reducing the environmental impact of production and disposal. This makes them a better choice for eco-conscious consumers.
