Laser engraving glass

Engraving on hollow glassware, flat and special glass

Glass types suitable for processing with a glass engraving laser

Simple and precise glass engraving with a Trotec laser etching machine. Laser etching glass produces a fascinating matte effect. Very fine contours and details can be etched into glass as photos, lettering or logos, e.g. on wine glasses, Champagne flutes, beer glasses, bottles, mirror or window glass. Personalised gifts for parties or corporate events are eye catching and laser etching glass gifts can help you to make a lasting impression.

Application examples for engraved glass


Similar to so-called "matting" of the material, glass is only superficially etched by the glass engraving laser. With Trotec laser machines finest details can be accurately applied to the material as clear, white glass etchings. For glass etching with a laser on conical objects (e.g. beer glasses or bottles) we recommend that you use a rotary engraving device, which will automatically turn your work piece during the laser engraving process, so that it remains in the correct position. It is not possible to laser cut glass using a Trotc laser machine.

Why should I buy a laser for glass engraving?

No risk of breakage due to non-contact processing: With a glass engraving machine no templates are required unlike with sandblasting. The etching is done directly on the glass surface. If the glass must be engraved deeply by means of sandblasting, the laser etching machine will be useful for producing the perfect templates. Firmly apply the sandblasting film onto the work piece and cut out the motif with the laser device. The workpiece can then be sandblasted immediately.

Function and advantages of laser technology

Non-contact processing

  • No risk of breakage due to mechanical impact

Advantages of a Trotec laser

  • The rotary engraving attachment allows you to produce engravings across the entire circumference and is available for all platform sizes

Top engraving results in record time

  • There is no need to create a template unlike with sandblasting
  • Trotec lasers are as easy to use as a printer. Work in your usual programs and send your layout to the laser from your PC or Mac.
  • From single pieces to series production

Advantages of a Trotec laser

  • JobControl® laser software: Simply intuitive. Work efficiently.
  • Speedy series: The fastest laser engravers available on the market with a maximum engraving speed of 4.2 m/sec and an acceleration of 5g.
  • Trotec offers the largest product range and the greatest flexibility within the systems

Fine, accurately contoured details


  • Easy laser etching into glass surfaces of logos, individual texts and photos

Advantages of a Trotec laser

  • High-quality optics and beam quality

No tool wear


  • No wear of the laser beam results from the material processing
  • No costs for new tools unlike with classic engraving methods

Advantages of a Trotec laser

  • CeramiCore laser sources with a particularly long service life

No dust exposure due to blasting agents

  • The glass is heated by the laser beam on the surface of the glass and fine glass particles are removed. Compared to sandblasting no residual blasting agents are required.

Advantages of a Trotec laser

  • The resulting gases and particles are efficiently removed and filtered by the Trotec exhaust systems.
"The Sales Manager came out and did an on-site demonstration for us. This is something Trotec’s competitors weren’t willing to do for us, so we were immediately impressed with how accommodating they were."
- ​Chris Beard - owner and managing director of Collective Design -
"I decided to choose Trotec because I know that they have been associated with quality and craftsmanship for many years. The laser is working well and any problems I’ve had have been handled admirably by the Trotec team."
- John Edgington - Scojo -
"We found Trotec through one of their shows and we had a great experience with them from the get go! We used to just sell wine, but now we can offer our customers a full bottle and box customisation service, which has allowed us to expand the business."

Tips for laser engraving glass

Can round or conical objects be engraved?

Yes. By using a rotary attachment, round and conical designs can be engraved along the entire circumference. The JobControl® laser software provides all the necessary parameters. You only need to enter the diameter of your workpiece and the height of the graphic, and you are good to go.

Can the material break during laser engraving glass?

Depending on the type of glass and the lead content, slight cracking may occur, meaning results will vary between jobs. Place a damp paper towel on the laser engraving area. This dissipates the heat better and prevents any cracks occurring when laser engraving and laser etching glass. Cheap glass can often be engraved easier than crystal glass; the reason is the higher lead content.

How can I get a clear engraving result when laser engraving glass?

The use of a wet paper towel not only prevents the glass from cracking but also leads to a clear, white engraving result. The important thing is that there are no air bubbles or wrinkles in the paper, as these irregularities might otherwise be visible when laser engraving glass. Please also make sure that the Air Assist is disabled, otherwise the airflow can dry the wet paper prematurely. Alternatively, you can also use masking tape. To minimise the effect of the heat on large surfaces and thus optimise the engraving result, the graphics should be converted to gray scale (e.g. black graphic into 70–80 % black). In this case, no wet paper towel or masking tape is necessary.

How to get the best effect when photo laser engraving glass?

Use gray scale rasterisation of 70% black; thereby somewhat less heat is applied to the glass, improving the result. We recommend an average resolution of 500 dpi and the use of the “ordered dithering” rasterisation method; this fits the image data optimally to the material.

Can mirrors be engraved as well?

Engraving or laser etching glass mirrors allows you to create an extraordinary decorative element out of any standard mirror. When using the fiber laser, you can engrave the mirror from above through the glass. The glass does not react with the fiber laser, so only the mirror layer is ablated. The glass itself is not scored as it only responds to the wavelength of the CO2 laser source. The subsequent cleaning is very easy to do, because the material removed by the engraving falls onto the table beneath the mirror, and little dust is left on the mirror itself. Acrylic lacquer is applied to the back of the mirror. The positive effect on the mirror: The laser-engraved part of the glass has no mirror layer and is transparent. Thus, the colours of the lacquer remain bright and intense through the transparent glass.

Can I cut glass with a glass engraving machine?

Trotec laser machines cannot cut glass. laser etching lass and engraving are the only processes which can be completed.
