One of the most important glass properties is its ability to to take on the most varied of configurations by molding.

In order to fix the shape obtained, the products are cooled to an even lower temperature at which the molten glass completely loses its flowability.

In this way, there is a change in viscosity of the glass melt Depending on the temperature, it is the most decisive factor in the process of forming glass products. Thanks to the fact that glass can have practically any degree of viscosity, the most diverse shaping processes can be used with respect to glass use.

Taking into account the reversibility of the law of dependency the viscosity of the molten glass and the temperature can be used to create a particularly complex shaping regime with multiple touches Perform glass mass to be formed with elements of the forming device.

In modern automatic feeders of the glass forming machines, the surface tension also acts as an important factor, without which it would not be possible to give the glass mass that is drawn into the forming device the desired shape.
