Tempering - flat glass (market for)

The activity generating the emissions is market for tempering, flat glass. The reference product is tempering, flat glass. The service "tempering, flat glass" represents the toughening of 1 kg of glass, a special process of solidification of a glass sheet in order to make it particularly resistant to breakages. The glass sheet is heated to a temperature just below its softening point (about 640°C, thermal tempering) and then immediately cooled by special jets of cold-air. These harden the surface of the glass, giving the inside more time to cool. This allows the external layer to crystallize into a wider lattice while the inside solidifies with greater compression than in the crystal lattice. The most common application is automotive glass. A user employing this module should add the respective amount of raw glass, as the throughput of raw glass is not included. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary market activity.
