Engraving On Stone, Granit, Slate, & Other Minerals

Discover our stone engraving machines, laser and rotary!

There are 2 kinds of engraving on minerals, depending on the composition. Laser etching is mainly for slates, tiles and bricks. Such materials react with white color when lasered, which gives a naturally contrasted result. Deep laser engraving for marble, granite, basalt, lava stone, natural stone, pebbles, ceramic, porcelain, and black granite, will give a non-contrasted or slightly contrasted result. 

Often, paint or lacquer is added afterwards to get a nice colored result. Cutting minerals is not possible with a laser. Engraving Granite or Marble with text or a photo is an ancient Funeral tradition (mainly in Europe and South America). Now, engraving on different kinds of stone is very popular in new markets like jewelry, interior design and crafts, events, gifts, and signage.

Laser Engraving

Laser engraving on minerals produces a result similar to sandblasting, a surface engraving that gives the impression that the stone has been bleached. If the contrast is not sufficient for your customer or if you want a specific color, Gravotech offers the popular “Gravolaque”, lacquer range that comes in yellow, green, blue, red, white, black, silver, gold, and shiny gold available as standard, however your specific color can also be developed on demand. Gravolaque is suitable for indoor and outdoor applications.

Photo engraved on mineral

Engraving photos on minerals can be complex, as it depends on the surface state. Generally, the rule of thumb is to set 300 DPI maximum on the photo resolution to obtain a nice result. This resolution can be increased if the surface state is similar and smooth. We recommend using very dark black marble (or very light white marble) so the contrast is even more beautiful. Gravolaque will always be necessary as marble does not contract naturally when engraved with a laser. A 1.5’’ lens is recommended for photo engraving with a thin spot beam.

Stone engraving with "I Love You"

Minerals are not flammable, therefore stone laser engraving has a limited risk of fire ignition, contrary to Acrylic or Wood processing, as they need to be monitored.

    Rotary machines can process minerals (engrave only), but we recommend it only for expert users, as bur diamonds are required and they can be very expensive. Moreover, the risk of cutter break increases as the granite quality decreases. Granite is mainly used for headstones and other memorials and images of loved ones or logos can only be engraved on granite using laser equipment.
