Stone, granite and slate laser engraving
Engrave and personalise minerals such as stone, marble, peebles and slate with Gravotech engraving solutions.
There are 2 kinds of engraving on minerals, depending on the composition:
Laser etching mainly for slates, tiles and bricks. Such materials react with white colour when lasered, which gives a naturally contrasted result.
Deep laser engraving: 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 coloured result.
Cutting minerals is not possible with a laser engraving machine.
Engraving Granite or Marble with a 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 Jewellery, interior design and crafts, events, gifts, and signage.

Stone laser engraving
Laser engraver for stone 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 colour, Gravotech offers the popular “Gravolaque” lacquer range: yellow, green, blue, red, white, black, silver, gold and shiny gold are available as standard however your specific colour can also be developed on demand.
Gravolaque is suitable for indoor and outdoor applications.

Engraving photos on minerals can be complex as it depends on the surface state.
Generally, the rule of a 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 stone laser engraving machine.
A 1.5’’ lens is recommended for photo engraving with a thin spot beam.
Minerals are not flammable, therefore laser engraver for stone has a very limited risk of fire ignition, contrary to Acrylic or Wood processing when they need to be monitored.
