Step 1

Raw materials

The main components come from nature.

  • Silica sand
  • Sodium carbonate
  • Limestone
  • Recycled Glass

Step 2

Merging

The mixture is melted in furnaces at a temperature of around 1,500ºC, converting the mixture of raw materials into molten glass.

When it comes out of the kiln, it is cut into molten glass "drops" of a certain weight.

Step 3

Mould

The glass droplets are placed in moulds where they are blown into the desired container shape.

Step 4

Annealing chest

To ensure the solidity of the glass containers, they are placed in an annealing chest where they are cooled in a slow and controlled manner.

Step 5

Quality control

Every single pack is subjected to strict automated quality controls. Defective packaging is melted again in the furnace.

Step 6

Paletising

The packages are palletised and hermetically sealed so that they reach the customer in the best possible condition.
