The agenda and the participants of the 40 years ago Mont Louis International Colloquium on Solar Energy are looked at, and it is obvious that the bulk of the meeting is devoted to solar furnaces although not exclusively. This coïncides to the profile of the CNRS Solar Energy Laboratory founded in 1948 according to the will expressed in a motion signed by 11 academicians all specialists in the field of high temperature and inorganic chemistry and metallurgy. At the issue of a campaign of research in using a solar furnace in Meudon there were enough evidences established by Tombe's team to justify the construction of a large solar furnace for new high temperature capabilities and practical applications on hand. The main contributions by Trombe and Foëx are identified to be : the non contaminant self-crucible melting using focused solar radiation, the hot spot specific features and the coupling of solar furnace and other sources like plasma gun. The analysis of different cases of high temperatures approaches since Moissan with his electric furnace all through today's research shows a surprising continuity in efficiently creating new objects in the sense of M.Berthelot.
