Adding a text, a logo or a picture on glass is necessary for personalizing a lot of different items: On wine glasses, beer glasses, champagne flutes, or bottles for a gift, for a special event, or as a promotion tool Perfume flasks or candles On mirrors or jars for decoration On trophy or awards On photo frame It can also be used for other purposes, like windows signage or identification on glasses. Glass can be marked in different ways:
Engraving is the only method that will suit for any type of glass and last on your item, even after several dishwashes for glasses.
Engraving on glass will only affect the surface of the material and “depolish” it. The result is a very nice frozen aspect that enhances the item. Other aspects can be obtained with a laser by playing with the parameters. Laser engraving roughens the worked surface, while mechanical diamond engraving hollows out the material to deliver a thinner engraving while maintaining its transparency. Even if glass engraving is colourless, adding colours to the engraved design is possible by applying different colourants, also offered by Gravotech. This is ideal to get a golden engraving on a wedding glass for instance. Laser will create your photo on the glass, line per line, creating a special moment for your customer. Custom glass engraving is a very valuable business, both technologies will ensure a fast return on investment.
Laser is particularly recommended for photo or logo engraving as the results are spectacular and even the smallest details can be engraved on glass. The most popular accessory of our glass engraving machine is the rotary device, as it will allow the laser to engrave all around circular items by automatically rotating them on 360°. Note that glass cannot be cut by a laser.

Engraving glass with a Laser avoids the risk of breaking the product or the tool. This contactless technology ensures a safe engraving, even on the thinnest glass and it is noiseless.
However, cracks naturally appear when glass is lazed, mostly depending on the glass quality (crystal is usually crack free). To reduce that, we recommend laying a small wet paper on the glass processed area before lazing it. This will improve the heat dissipation and therefore reduce cracks effects. When using this technique, do not forget to turn off the air assist to avoid drying the paper.
By playing with the focal distance and laser power, different aspects can be obtained with laser. Depending on the result you want, the laser parameters will be adapted automatically thanks to our Gravostyle™ software library.
It allows the user to process:
Mechanical engraving will result in a light engraving, looking like a traditional manual engraving. Mechanical engraving is ideal for vector engraving, calligraphic text and outline logos. A diamond tip physically engraves the material. It ensures a perfect result whatever the glass composition.
Adding lubricant avoids microcracks and leads to a fine and clear engraving.
See our rotary glass engravers.
Depending on the pressure applied on the glass, the engraving can be deep enough to be filled with colour or it can be light and create a depolish effect that only affect the surface of the glass.
Mechanical engraving machines are cheaper than lasers, moreover, as there is no need for an air exhaust (contrary to the laser) the using cost is very low and the return on investment is faster.
Mechanical engraving is a compact solution and designed to be used in-shop. They are very popular to personalise small items like flasks live to create an unforgettable moment for your customers.
Mechanical engraving machines can be easily upgraded to open new possibilities, for instance with a rotary device to engrave on circular items or with a lubricant tray to retrieve glass dust carried by the lubrication system.
Gravotech lasers are ideal for unit or small batch glass engraving, as even the smallest lasers (40W) are powerful enough for custom glass engraving. A Laser engraver also allows you to engrave on wood, plastics, or any other organic material.
