Sharp knives and glass cutters are useful instruments for cutting or scoring glass and other materials. Saw blades may also be used to cut large sheets of glass. The saw must be applied with caution not to break the glass.
Other tools that can be used for cutting glass include axes, hatchets, and machetes. These tools can usually only cut very thin slices of glass, however.
Finally, electric power tools can be used to cut glass. These tools are available as hand-held units or mounted in a benchtop unit. They are effective for cutting small pieces of glass, but cannot slice through thicker glass sheets.
Glass is a brittle material which breaks easily if struck hard. Therefore, handle glass with care and do not expose it to excessive force or pressure when cutting.
The type of knife used to cut glass will determine how well it can be done. For example, a sharp paring knife will be able to cut away tiny details from around windowpanes while leaving the actual windowpanes intact. It would not be able to cut through a thick sheet of glass though.
A utility knife or craft knife will have a more general use and could be used to cut through most types of glass.
The challenge is to find something hard enough to scratch the glass while yet being comfortable to hold in order to achieve a tidy, clean line. Some of the most common instruments for cutting glass include: A glass cutter is a tool that has a hardened steel cutting wheel that is used to score an equal line through glass. The glass is then broken along these lines by applying pressure from outside the instrument.
A hacksaw can be used instead; however, it's easy to distort the cut if you aren't careful. Glass is made up of many small crystals that are bonded together by a transparent resin. If you saw right through the resin, you would just as easily saw your way through your hand! Hacksaws are also not recommended for use on window glass because they will leave jagged edges that could damage other items inside your home.
Finally, a knife can be used for cutting glass. However, this is the hardest material you can work with and requires skill to do so successfully. Also, be sure to wear protective gear such as gloves when using a knife to avoid cuts or injuries.
Glass can be cut with ease using a glass cutter. These tools are available at hardware stores and some home improvement centers. They look like large scissors but rather than closing, they have a rigid metal rod within the handle that gets bent during use to provide a sharp point.
Engraving, cutting, and etching In general, glass can be sliced by melting it with a high-energy laser. High power can be used to cut thin glass (when employing specific cooling methods) or stained glass (400 W). Slower but more precise cutting can be done with a diamond blade or other tool. Glass can also be cut by grinding it with very hard materials such as silicon carbide or sapphire. Laser engravers use similar technology to etch designs into glass substrates for visual effects.
Lasers can also be used to burn or melt materials. The carbon dioxide laser is used for cutting metals because it creates heat that causes surface cracks and breaks. The same laser beam can be focused on a small spot to heat and vaporize materials or large areas can be burned at once. A special type of laser called an excimer laser can spark chemical reactions in gases that produce exotic molecules not found in nature. These lasers are used in science labs to synthesize compounds that are useful for medicine or materials processing.
Laser light can also be used to kill bacteria and cancer cells. Lasers used in medicine are called laser pointers or medical lasers. They are usually diode-based devices that emit light in the red or infrared spectrum.
Glass chopper. Also called glass cutter, glass mill, or glass beater.
There are two types of glass cutters: those that use a sharp blade and those that use a grinding wheel. Grinding wheels are more durable but require periodic replacement. Sharp blades can be replaced but grinding wheels cannot. Glass choppers are available in many sizes and shapes. The type you select depends on how much work you plan to do with it. If you plan to grind only small amounts of glass, a hand-held unit will suffice. Otherwise, look for a benchtop model.
The cutting action occurs because of the weight of the tool. The blade is angled under the table to allow your hand to move quickly from piece to piece without straining yourself. Hand-held units are easy to use and quick-cutting tools that can slice through almost any material. They are good for smaller pieces of glass. Benchtop models weigh more and are designed to hold larger quantities of glass. They are not as easy to use but can handle most any size fragment.
Tool safety is an important consideration when using any tool.
