How to distinguish between silver mirror and aluminum mirror?

1. First of all, look at the clarity of reflections of silver mirrors and aluminum mirrors
Compared with the lacquer on the surface of the aluminum mirror, the lacquer of the silver mirror is deeper, while the lacquer of the aluminum mirror is lighter. The silver mirror is much clearer than the aluminum mirror, and the geometric angle of the object light source reflection is more standardized. The reflectivity of aluminum mirrors is low, and the reflection performance of ordinary aluminum mirrors is about 70%. The shape and color are easily distorted, and the life span is short, and the corrosion resistance is poor. It has been completely eliminated in European and American countries. However, aluminum mirrors are easy to produce on a large scale, and the cost of raw materials is relatively low.
2. Secondly, look at the distinction between silver mirror and aluminum mirror back coating
Generally, silver mirrors are protected by more than two layers of paint. Scrape off part of the protective paint on the surface of the mirror. If the bottom layer shows copper, the proof is a silver mirror, and the proof that shows silver white is an aluminum mirror. Generally, the back coating of silver mirrors is dark gray, and the back coating of aluminum mirrors is light gray.
Again, the contrast method distinguishes silver mirrors and aluminum mirrors
Silver mirrors and aluminum mirrors can be distinguished from the color of the front mirror as follows: silver mirrors are dark and bright, and the color is deep, and aluminum mirrors are whitish and bright, and the color is bleached. Therefore, silver mirrors are distinguished by color alone: ​​the color on the back is gray, and the color on the front is dark, dark and bright. Put the two together, the shiny, whitish aluminum mirror.
3. Finally, compare the active level of surface paint
Silver is an inactive metal, and aluminum is an active metal. After a long time, aluminum will oxidize and lose its natural color and turn gray, but silver will not. It is simpler to test with dilute hydrochloric acid. Aluminum reacts very strongly, while silver is very slow. Silver mirrors are more waterproof and moisture-proof than aluminum mirrors, and the photos are clearer and brighter. Generally, they are more durable than aluminum mirrors when used in damp places in the bathroom.

The “silver mirror” uses silver as the electroplating component, while the “aluminum mirror” uses metal aluminum. The difference in material selection and manufacturing process still makes the two bath mirrors very different. The refraction performance of “Silver Mirror” is better than that of “Aluminum Mirror”. Under the same light intensity, the “Silver Mirror” will appear brighter.
