A jump into the past
Throughout history, gold has been prized for its natural beauty and splendor. For this reason many cultures have imagined that it could represent the sun.
How many times have you stopped to look at a jewel because you were fascinated by its aesthetic beauty? Since ancient times, men and women have adorned themselves with precious objects to embellish themselves and appear in the eyes of others.
Precious metals and jewels have been part of humanity since prehistoric times.
Our ancestors wore jewelry made of feathers, bones, shells and colorful pebbles. Diamonds only began to spread in Europe around 1300, when men learned to cut them to show off their brilliance.
Many types of jewelry were used as ornaments.
Rings and pendants were used as signs of identification, worn especially by authoritative figures who had to affirm their position within a group.
The first discovery of jewels dates back to approximately 25,000 years ago.
It all started from a need: the need to feel accepted, to belong, to take care of one's body. In early societies, jewelry was worn as amulets to protect against bad luck and disease.
Jewels later took on a different value and began to be used as a promise of love between two people in love who undertake to take care of each other. Slaves were made to wear bracelets as a form of identification. At one time in Europe only wealthy, high-ranking church officials were allowed to wear gemstones. This was a sign of wealth and power. Ordinary people who wished to imitate them could wear less expensive jewelry.
From precious metals to jewels
Before becoming jewels, precious metals undergo manufacturing processes that require attention and the use of a certain level of equipment.
Let's see together the phases that lead to the creation of a jewel:
- Extraction of precious metals from mines
- Modification process, to separate precious metals from any impurities
- Smelting and refining process to go from solid to liquid form
- Modeling process
From these manufacturing processes we obtain semi-finished products that are not yet ready for sale. Finally, to become precious objects, precious metals are subjected to manufacturing processes using artisanal or industrial techniques.
Artisanal techniques, compared to industrial ones, follow a different manufacturing process, with greater attention to detail.
How the precious metals processing sector has evolved and how Cryotek Eng is positioned
Who doesn't wear at least one piece of jewelry? The needs that drive us to purchase a gold object are the same as millions of years ago.
Precious metals that existed in ancient times are now subjected to more complex manufacturing processes.
In recent years there has been a technological evolution that has led to the creation of increasingly fascinating, beautiful and sophisticated jewels.
The gold industry had a strong development in Italy in the 60s and 70s and Cryotek Eng was a participant in it with its equipment and research.
New line of gas mixing systems for the gold industry
Cryotek Eng has created systems for creating mixtures for heat treatment ovens, responding with its products and services to the most varied market requests.
A new line of gas mixing systems has been studied, with a new design, easy to install, adaptable to any production process: Gas mixing system MOD. GoldMixer .
Not only that, a line of flame micro-mixers has also been designed which have the function of modeling the gold and a series of specific torches for the gold sector.
The evolution of Cryotek Eng has led to the study and engineering of complete systems for the conditioning of welding gases and the heat treatment of precious metals.
Cryotek Eng takes on a significant position in the gold sector, offering customized products and after-sales assistance that allows it to intervene promptly anywhere in the world thanks to its team of technical designers.
Every jewel hides a beautiful story behind it and Cryotek Eng is a full part of it.
