based on the statements of section 1 of this chapter it can be postulated that real polyhedron foam glass bodies are only derivatives of an ideal foam in accordance with the principles of J.Plateau, whose cellular structure consists of a multitude of space-pervading congruent base polyhedra. As elementary polyhedra of this ideal foam glass, which are described in section 1 of this chapter as archetypes of the base polyhedron of a real polyhedron foam glass, today only the α-tetradecahedron of Kelvin and the β - tetradecahedron of R.E. Williams. Here, the statistical distribution of the types of polyhedron surfaces within an ideal foam, whose cell structure is composed of many β- tetrahedrons most closely corresponds to the conditions in nature as with the “Kelvin foam”.

From the statements in section 2 of this chapter it can be concluded that the temperature profile of the foam expansion process as well as the starting mixture exert a significant influence on the morphology as well as the regressions between the density ρ and the parameters n* and L̅_3.

With this, it is evident that the prominence of the relationships referred to is lost at higher expansion temperatures.
