At the same time, with a diamond glass cutter placed on a ballerina, you can easily cut out arcs, circles and even round holes in the glass.
Manual glass grinding
The cut fragments, as a rule, have sharp edges and edges that can easily injure your hand or fingers. Therefore, it is necessary to process the edges of the glass using a machine or smoothing on edge wheels. Most often, the device for wiping edges is a low-speed motor with a special abrasive wheel or a wooden block onto which fine sandpaper is glued.
Treatment is carried out with periodic wetting of the edges with water and abrasive paste. The result is a smooth, slightly rough surface. If you use diamond paste or a glass edge processing machine instead of an abrasive paste, you can achieve absolutely smooth edges. In a similar way, glass and mirrors are processed using high-speed precision rollers and a diamond suspension on polishing equipment.
How to quickly sharpen glass?
To make the process easier and faster
, kerosene or turpentine is used to wet the instrument.
For filing glass
, especially thin glass, smooth movements are used. If possible, the surface to be treated is placed under a water jet.

Mirror edges: euro-edge and its types, home method of polishing the perimeter
Today we are talking about the edges of mirrors, for example, euro-edging is professional edge processing, otherwise grinding and, in addition to this work, polishing the end of a new mirror. The manufacturer also offers straight and shaped edges, informing the buyer in advance that processing the edge of any glass can significantly reduce residual stresses inside the glass, reducing the likelihood of large cracks and multiple chips during installation, as well as addressing the issue of expanding the possibility of modernization product by changing the design.
The processed edge of the mirror gives the glass product a presentable appearance, clearly emphasizing both its individuality and safety. Polished Euroedge has long been used in furniture production and in the manufacture of countertops, large and small partitions, mirrored steps, glass doors, and so on.
Mirror edge: beauty and safety
Glass for our mirrors is a ready-made material, which, of course, must be processed so that in everyday life it does not cause harm to the objects and people around it. Existing standards for flat sheet glass for creating special elements do not always accept one form or another for the interior. But we will now resolve this issue: mirrors are cut on special machines, the processing of their reverse side is changed, thereby obtaining a mirror made of reinforced, laminated, tempered and other types of glass.
Glass cutting is done with a diamond tool - a glass cutter. This household and fairly simple tool consists of a handle-holder and a diamond roller secured to it. To cut circular glass, you will need a compass tool, but it is best to buy a cutting table with a full automatic mode and carries out work with an accuracy of half a millimeter.
After cutting the mirror, you will need to grind its edges and then polish them.
Let's understand the process of grinding an edge with a coarse-grained material, which results in a rather rough surface with a matte finish. It’s ugly, of course, to hang such a mirror on the wall, especially since a processing angle of forty-five and even ninety degrees turns the product into a rough blank.
Roughness is removed by polishing, and this process is carried out on glass of both curved and rectilinear shapes. At the same time, the processing angle remains the same, but a fine-grained image is put to work. Step by step, the perimeter of the mirror is polished, and the work is done until the sides of the product become transparent.
With modern equipment, any polishing of a mirror is done using grinding wheels, but they have a diamond coating. The latest grinding machines not only work according to a given program, but are also ready to create contours such as a flower, a butterfly, a curved trapezoid, and so on. If you are familiar with the cascade mirror, then you now understand what we are talking about. Grinding of such products is carried out on a modernized washer machine. How? It’s simple: a mirror is placed on a disk rotating in a horizontal plane, and a stream of water is applied to its edge under pressure, to which either a formative powder or sand of a certain grain size and composition is mixed.
But mirrors are brought into proper condition on tape machines. Here the edges of the mirrors fall into the power of rotating rollers mounted on a special tape. To protect the glass from overheating, the edge is also cooled with water and abrasive powder. Such a machine produces only straight-line products, allowing you to significantly reduce its cost.
Processing the ends of both glass and mirrors allows the manufacturer to reduce residual stress on the product, sending products that are safe for living beings to the retail counter. In addition, the above procedure is always carried out before tempering any glass. Now not only is the edge quite strong, but the whole mirror is too.
Mirror polishing, like its grinding, is visible on display shelves, numerous counters, coffee and dining tables, aquariums, terrariums, bathroom shelves, and so on. Ordinary glass is polished more easily, using rotating grass brushes, which are pre-impregnated with pumice-water emulsion.
There is another way of polishing, for example, by dipping into a composition of two acids - sulfuric and hydrofluoric, and then into clean water. The number of such dips depends on the technological requirements for the product in its final stage and the degree of gloss of the edges.
Ways to prevent scratches on glass
- The favorite method of washing glass, which uses newspapers, is actually unacceptable. If our ancestors could still do this without damaging the glass surface, now rough paper and ink with many impurities are allowed in the production of newspapers. All this makes such a product a real abrasive;
- Various washing or cleaning powders are best used only if they are completely soluble in water. Otherwise, their particles will cause damage to the glass;
- To wash glass, it is recommended to use soft materials that do not leave marks, as well as products specially created for this purpose. The latter are constantly being improved, so that their ability to clean glass surfaces safely has increased greatly in recent years;
- If during the glass washing process aggressive cleaning agents or hot water were used, then after washing it is not recommended to wipe them with hard, dry rags. This approach practically guarantees scratches on the glass.
Tools for work
At home, this material is usually sanded and polished. To carry out these steps efficiently, you should acquire the following tools:
- Drill.
- Glass cutter.
- With pliers.
- With a file.
- Grinder with the ability to change the rotation speed. This is very important, as it is necessary that the fragile material does not overheat.
- An attachment with Velcro, which will be used to secure the grinding wheels.
- Grinding wheels of different grain sizes. Their surface should be sandable and resistant to moisture.
Important! Glass is not only expensive, but also an unsafe material. To avoid injury, wear protective goggles over your eyes and cotton gloves on your hands.
Glass processing at home - we present it in detail
Glass is a very fragile material, but many useful and beautiful things can be made from it. Besides, you can’t do without it: it’s in the windows, dishes are made from it, and much more. How is it made? If you don’t know yet, we will reveal how glass processing is done at home, because it consists of several stages. With the help of the information in this article, you can try your hand at this by creating decorative items for your home.
Mirror edges: bevel processing
What is bevel processing for a mirror? This is a technology in which sharp edges are removed from the edge of glass. How does this happen? Three ways:
- dulling the edge with a special high-quality abrasive tool;
- polishing the edge, but with a fine-grained abrasive, until a transparent surface is obtained, called "optical clarity".
grinding the edge, but with a coarse-grained abrasive and until a certain matte cut surface is obtained;
The processing of the mirror edge is carried out using specially prepared equipment, but you can process the glass edge yourself. Industrially, different profiles are produced, for example:
Grinding edges and polishing mirror blanks is simply necessary in the production of furniture fittings, in the production of commercial equipment for halls, in the design of various themes of exhibition stands and where designers use glass, and with an unclosed edge.
Do-it-yourself mirror edge processing
Do you want to know how to make glass grinding and polishing for a mirror, but with your own hands? buy for this:
- an electric drill or grinder, but with a speed controller, and the rotation speed is low (up to 1700 per minute), otherwise the glass can overheat;
- a special attachment with Velcro to firmly attach the grinding wheels, and the wheels themselves will have to be purchased with waterproof sandpaper of different grits.
- Attach your attachment to the drill, insert a disk, but first a large one (about 100 or 200 grit), grind it, removing jagged irregularities, forming an edge.
- Grinding is carried out even with emery, but having previously secured your grinding wheel (necessarily with diamond coating) of a certain profile or immediately flat.
- The edge of the glass is drawn in advance: either semicircular (like a pencil), or trapezoidal (like a euro-edge), or asymmetrical trapezoidal; otherwise, you can draw another with a mark. Once the granite is matte and rough, proceed to a new stage.
- We treated the surface with a large disc, now it’s up to the disc of 300 or 600 grit, and finally 1000 or 2000 grit.
- Do all the work under a thin stream of water (so you will need an assistant one hundred percent).
- Once everything has worked out, it’s time to polish the product, but for those that will go into the frame, it is not necessary to do such work. Do-it-yourself polishing is done using a soft felt circle and a special GOI paste.
- Apply it to a soft felt circle, polish the edges of the future mirror to a shine using a drill with an attachment, a grinder or a felt circle, placing it on sandpaper.
- Do not overheat the glass, do not rush, work with special gloves and goggles.
First stage of processing
When the initial rough processing of the edge of the glass is performed, it will become not only smooth, but also safe. However, the surface still remains quite rough.
Do-it-yourself processing of the glass edge is done using ordinary pliers or the side recess of a glass cutter:
- The glass should be grabbed in small sections, breaking off pieces two to three millimeters in size.
- Use pliers to remove smaller projections. In this case, you need to firmly grasp the material and gently squeeze the tool.
Alternative to polishing
If the scratches are not very deep, and there is no desire to do polishing work (especially since this is a rather long and labor-intensive process), then you can use methods for masking scratches. Typically, compositions based on transparent materials with wax-like properties are used for this. But this effect does not last forever, and in the case of major damage it may not help.
Important! If you don’t have any specialized products at hand, which happens quite often, then transparent nail polish would be the ideal solution. Before applying varnish, the surface must be well cleaned. After application, let the varnish dry a little and remove excess using a rubber spatula.
