Engrave Granite With Laser
There are many materials suitable to engrave with laser. In previous posts I have written about these materials. You can tak a look at:
- Engraving Materials: Stone
- Engraving Materials: Metals
- Engraving Materials: Plastic
- Engraving Materials: Wood
But is the laser engraving technique adequate for Granite?
Yes, granites are usually a white or buff colour and are medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
Outcrops of granite tend to form tors, rounded massifs, and terrains of rounded boulders cropping out of flat, sandy soils. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.
Granite is nearly always massive, hard and tough, and it is for this reason it has gained widespread use as a construction stone.
Stone tile is an incredible material that yields impressive and profitable results when laser engraved. The best choices for engraving is Indian Premium Black Granite (IPBG). The reasoning behind choosing a black material is simply because other colors just don’t provide enough contrast to stand out and command attention.
Indian Premium Black Granite is available in most tile stores/outlets and may be found under various other names. Just ensure that the specks are the smallest possible and that the material is close to a solid black. The smaller the specks, the less chance of a ‘washed out’ image effect. Granite specks are similar to marble veins, which if overwhelming, make the lasered image lose the focus of the material.
