Laser engraving is gaining popularity not only among professionals but also among artists. It consists in applying patterns, symbols or inscriptions on the surface of various materials.
What is engraving and where did it come from?
Originally, engraving meant working with metal and was classified as a metal craft. However, this ancient method has not only evolved technologically over the centuries, but has also been applied to very different materials. Stuff was getting engraved in wood, in bone or in stone. Today, “engraving” in various materials other than metal has actually become so ingrained in the language, that the term in this context can hardly be called colloquial anymore.
Beautiful jewelry items and other ornaments were also created with engraving over the centuries. For this purpose our ancestors used styluses – skewers with different handles and tips. The cutting of the material allowed the creation of unique ornaments depending on the style of the craftsman.
An engraving found in South Africa of ostrich eggshells used as water containers dates back 60,000 years. Among the Sumerians of Mesopotamia (Neolithic, Bronze Age) and the Hittites of what is now Syria and Palestine (Bronze Age), decorative engraved gemstones, such as soapstone and lapis lazuli, were popular.
The following material presents a little more modern approach to the topic. Easter eggs and caskets made of ostrich eggshells by Leszek Klysewicz, an inhabitant of Horyniec-Zdrój in Eastern Roztocze. Truly beautiful. They reminds us of Fabergé eggs from the times of the Russian Empire.

Laser engraving
Over the years – and we are, after all, skipping centuries in zooming in on this tale – engraving lasers emerged. These devices, in which the radiation source is solid, produce a beam with a specific wavelength. They are used primarily for marking metals. Their galvano scanners enable fast and very precise work. They are applied in industry and in all places where fast, multi-volume marking is necessary. Under this group there are neodymium lasers. Neodymium is a chemical element from the lanthanide group, which is used in the production of catalysts and neodymium magnets.
Another engraving method used today is mixture of gases as a radiation source. Devices based on this method produce a beam that allows engraving with a really wide range of materials. Above the work table in the XY plane there is a moving head that emits the laser beam.
This is where the three main heroins of our article arise:
