HEXONET in partnership with PremiumSale.com is making available a limited number of premium domains through auction. Join for FREE at PremiumSale.com and start. The initial step in mirror manufacture involves cutting and shaping the glass blanks. Cutting is usually done with a saw with diamond dust embedded in. Non- opaque coating is layered over the thin, metal. This. allows a viewer on the other side, in a darkened room, to see through. It reflects. only about 4 percent of the light which strikes it. It does, however. This means. that the glass contains very few pits after polishing and will form an. When the metal layer is. Glass is also. considered a good material for mirrors because it can be molded into. Glass sheets are made from silica. Glass made from natural crystals. There are also synthetic glasses. The silica, or quartz, is. These usually contain some other chemical component to strengthen. Pyrex. for example, is a borosilicate glass—a glass composed of silica and. ![]() ![]() In. particular, mirrors on children's toys are often made this way, so. Plastic polymers are manufactured from. They can be injection molded into. Metallic coatings. A variety of metals, such as silver. Silver was the most. More. recently, before 1. This practice. was also eventually abandoned, for it posed the problem of sealing in the. Today, aluminum is the most commonly used metallic coating. These types of coatings, referred to as. They are more scratch resistant than metal. Scientific. mirrors also use silver coatings, and sometimes gold coatings as well, to. Mirrors for household use must meet roughly the same. The glass sheets. The designer need only specify. Scientific mirrors usually have specially designed. These surfaces must be uniformly smooth within several l. OOOths. of an inch, and can be designed with a specific curvature, just like. Any subsequent layers of. For most common. mirrors, the reflective coating will be applied on the back surface of the. The back side is then. The initial step in mirror manufacture involves cutting and shaping. Cutting is usually done with a saw with diamond dust. Next, the blanks are put in optical grinding. The reflective material is. For standard visible light or ultraviolet. If the mirror is to be used. Dielectric coatings. Ultimately, however, the choice of. A dielectric coating, for. Coatings on scientific grade mirrors are usually. This is undesirable. If the mirror. is for an. Although some mirror manufacturers cut their own glass, others. Regardless of who. Diamond scribes or saws—sharp metal points or saws. The cutting method used depends entirely on the final shape the. In one method, the blades or scribes may be used to. In another method, a machine uses a diamond. Cutting. is usually done before the metal coating is applied, because the coating. An alternative to. These machines. consist of large base plates full of depressions that hold the blanks. A grinding. compound—a gritty liquid—is spread over the glass blanks. The action is. similar to grinding spices with a mortar and pestle. The grit in the. compound gradually wears away the glass surface until it assumes the. Finer and finer grits are used until. They are only used in cases. A commercial optical grinder. This is much more efficient than hand grinding. Even. specialty optics can be made mechanically in adjustable equipment. Regardless of the coating material, it is applied. The evaporator is a large vacuum. It is so called because. Blanks are centered over holes in the. Metals can be heated to several hundreds or thousands of degrees. The. temperature and timing for this procedure are controlled very precisely. This method of coating. This effect is often used to intentionally pattern. Metal stencils, or masks, can be applied to the surface of. Silicon oxides. and silicon nitrides are typically used as dielectric coatings. When. these gases combine in extreme heat, they react to form a solid. This reaction product forms a coating just like metal does. Clear dielectric materials may be evaporated on top of metal or. Mirrors with silvering on the back of the glass, for instance. One- way mirrors are the. Is it sufficient to have 8. Does all 8. 0 percent have to bounce in exactly the same direction? A purse mirror might only be. The. image would be slightly distorted in this case, but the distortion would. If, however, a mirror is to be used. The tolerances on. Mirrors on the edge of a grinding plate or evaporator chamber. If there is a wide range of metal thicknesses or surface. The. surface quality is examined first visually for scratches, unevenness. This can be done with the unaided eye, with a. The position of the stylus. This is similar to the way. Like the record player, the drawback to a. The laser can be used for non- destructive testing.
