1) Brief description: 

     s – self-curing, n – after ceramic firing, a-s – curing from s condition

     a-n – curing from n condition

2) All information about cured condition is given according to the alloy:

     – Oxide firing 10min/ 960°C + 4x4min/ 960°C for yellow conventional bonding alloys

     – Oxide firing 10min/ 980°C + 4x4min/ 980°C for white conventional bonding alloys

     – Oxide firing 10min/ 800°C + 4x4min/ 800°C for LFC-systems

   Corresponding data are true under these conditions only.

3) The ceramic firing should be carried out according to the manufacturer's instructions.
