Venice, city of gondolas, but above all the city where the oldest glass factories were born and where the glass manufacturing process began.
In 1291 all the glass factories in Venice were forced to move to the island of Murano.
An edict from Doge Tiepolo, in fact, established that all the furnaces active in the center of Venice were transferred to Murano, in order to preserve the Serenissima from the frequent fires that unfortunately frequently broke out inside the workshops.
Even today Murano remains the reference center for the largest glass furnaces and laboratories.
Glass has a much older history .
Amulets and beads were made in Mesopotamia as early as 2500 BC. Subsequently, glass making moved to Egypt around 1500 BC.
At the time of the Crusades, Venice became the glassmaking center of the Western world until 1291, when glassmaking equipment was moved to the island of Murano. During the 15th century, history tells us that the Venetian glassmaker, Angelo Barovier, began making the first crystal objects. Towards the end of the 1500s, many Venetians moved to northern Europe, with the hope of finding a more comfortable life and where they could start the first factories. They thus managed to export the art of glass blowing abroad, using the Venetian method. After 1550, English glassmakers, taking example from the Venetians, also began working with glass. Glass production began to grow rapidly thanks also to the introduction of increasingly cutting-edge machinery. We find glass everywhere, on the table, in the workplace, on means of transport. How is a glass bottle made? Each process is chosen based on the type of glass bottle you want to make. Silica (sand), sodium carbonate, limestone and cullet (furnace-ready recycled glass) are combined into a specific mixture. The mixture is then melted at a high temperature in the furnace, until it becomes a molten material.
The liquid that comes out of the oven is ready for the molding phase.
The type of glass this mixture will produce is known as soda-lime glass, the most popular glass for food and drink.
Once the bottle is finished, it is removed from the mold and transferred to the annealing oven. This process allows the glass to cool at a consistent rate, eliminating internal stresses in the glass that could cause cracks or breakage. In order to guarantee the quality control that every production process must possess, the bottles are normally subjected to careful inspections. Bottles that have imperfections, including bubbles, cracks or misshapen areas, are removed from the production line and used as scrap. Glass is considered one of the most sought after valuable objects in the world.
Glass processing is considered one of the processes that increasingly requires the use of certified quality machinery.
The heat required during the glass manufacturing process comes from the mixing of different gases such as Hydrogen/Oxygen, or Propane/methane and oxygen.
Cryotek Eng has always collaborated with the most important companies involved in the production and processing of glass, taking care of the entire design of gas systems for the treatment and processing of glass. (from the cylinders to the mold area).
- Plant construction
- Plant engineering
- Work management
- Construction of systems for handling bulk solid materials
- Installation of the system
- Electrical system and automation.
Cryotek Eng offers suitable services for verification and calibration of all equipment.
The sampling instruments are certified in accredited laboratories.
Cryotek Eng acts as the sole point of contact for the end customer for the entire design, construction and maintenance process of the systems, avoiding the usual inconveniences caused by the simultaneous presence of too many suppliers.
Cryotek Eng is able to supply systems and equipment from the gas storage area, up to the final molding user.
In fact, it offers turnkey projects in order to serve the production area with:
- Mold lubrication systems.
- Gas systems for cutting and welding operations.
- Equipment for process gas analysis laboratories.
- Analysis of environmental impact and compliance with national and international regulations, with particular attention to PED and ATEX regulations.
The inspections are carried out by specialized technical personnel and a team of field-trained instrumentalists. It is worth remembering that for this type of system, compliance with current safety regulations plays a role of fundamental importance, given the presence of highly flammable gases that are usually used during glass processing.
Cryotek Eng guarantees highly efficient, safe and economical production management with evident reductions in gas consumption.
Each job is undertaken with passion and dedication by qualified professionals attentive to the needs of their customers.
