Mirrors are an integral part of everyday life and are found in bathrooms, bedrooms and cars. But have you ever wondered how are mirrors made?
First, using ordinary glass as raw material, a mixture of polishing powder and water is used for the grinding and polishing process. After that, the surface of the glass is cleaned with a high-pressure water gun, and then a layer of silver is plated on the back of the glass. In the subsequent inspection session, the main focus is to check the light transmission and surface quality of the mirror to ensure that there are no scratches, bubbles and no chipping at the edges.
Finally, the mirrors are cut into specific shapes as needed and the edges are polished and sanded to meet customer requirements. In addition to the traditional silver mirrors, there are also mirrors using cheaper backside aluminized mirrors. These aluminum mirrors are made in a vacuum so that the aluminum evaporates and condenses on the glass surface to form an aluminum film, which is less costly and has a good light-harvesting effect.
Now that we’ve set the stage, let’s dive into the various stages of mirror manufacturing.
The Raw Materials: Glass and Silvering
The process of making a mirror begins with raw materials. Most mirrors are made from glass, which is a common material due to its clarity and ease of processing. The first step is to cut the glass to the desired size, followed by cleaning it thoroughly. Once the glass is prepped, it is coated with a reflective material, typically silver or aluminum.
The glass is the most important part of a mirror, but the reflective surface is made of metals like silver or aluminum. The type of metal used for the reflective surface can affect the quality of the reflection and the life of the mirror.
The first raw material is glass. In most cases, float glass is used because it has a smooth, even surface that is perfect for the reflective layer. The glass is cleaned thoroughly to remove any dirt, oils, or impurities. Once cleaned, a thin layer of silver or aluminum is applied to the glass, creating the reflective surface.
This silvering process, which involves a chemical reaction, allows the mirror to reflect light and produce a clear image. Some mirrors, like personalised LED mirrors, might also have additional features like color-changing light or fog resistance, but the basic process remains the same.
The Silvering Process: Coating the Glass
After the glass is prepared, the next critical step is silvering. This is the process of applying a reflective metal layer, usually silver or aluminum, to the back of the glass. This layer is what gives the mirror its reflective properties and allows us to see our reflection clearly.
Silvering is the process of applying a thin metallic layer to the glass to create the reflective surface. The most common metals used in this process are silver and aluminum.
In traditional mirror-making, silver is applied to the surface of the glass by using a solution of silver nitrate and ammonia. The chemical reaction between the silver nitrate and ammonia creates a silver film that bonds to the glass, creating a mirror-like finish. Aluminum is also used, especially in mass-produced mirrors, because it is less expensive and more durable. In high-end mirrors, such as custom LED mirrors, the silvering process is carefully controlled to ensure a high-quality, flawless finish.
Adding Protection: Backing and Coating
Once the reflective layer is applied, the mirror’s surface needs to be protected. This is done by applying a backing, which helps to hold the reflective layer in place and keep it from being damaged. A protective coating is then applied to maintain the quality of the mirror.
Mirrors are backed with materials like copper or paint to protect the reflective surface and enhance the mirror’s longevity.
The silver or aluminum coating that is applied to the glass is very delicate and can be easily scratched. To protect the reflective layer, a backing material is applied to the mirror. Copper is often used because it provides extra protection and helps to make the reflective surface more durable.
Once the copper backing is applied, a layer of paint or lacquer is added to keep the mirror from deteriorating and to prevent oxidation over time. In more advanced models, such as personalized LED mirrors, additional coatings may be added to increase functionality, such as water resistance or light diffusion.
Cutting, Polishing, and Edge Finishing
Once the mirror has been silvered and backed, it is cut to size and the edges are polished to remove any sharp corners. This ensures that the mirror is safe for handling and has an aesthetically pleasing finish.
After the mirror is backed and coated, it is cut to the desired dimensions, and the edges are smoothed and polished for safety and visual appeal.
The mirror is cut to size with a machine that is dead-on accurate, so the mirror fits perfectly where you want to put it (in your bathroom or on top of your vanity). Then the edges are smoothed and polished so you don’t cut yourself.
In some cases, mirrors are given beveled edges or decorative framing for a more refined look. For high-end mirrors like those offered by bathroom mirror manufacturers, extra attention is paid to the finishing, as this can significantly impact the overall look and feel of the mirror in your space.
Quality Control and Final Inspection
Before we ship it to you, we do a final quality control check to make sure that mirror is perfect, that it’s clear, that it’s reflective, and that it’s going to last.
Quality control ensures that every mirror meets the desired standards of reflectivity, clarity, and overall quality before being shipped.
The mirror goes through quality control when the reflective coating is applied. They check to make sure there are no flaws in the mirror’s clarity and reflectivity. They test to make sure the mirror is durable and won’t easily be damaged.
Any mirror that doesn’t meet our high standards is thrown away or sent back to be reworked. This is especially important with high-end products like custom LED mirrors because people expect a perfect, high-quality finish. Once the mirror passes quality control, we package it up carefully and ship it to you.
FAQS
What Are Mirrors Made Of?
