Personally I simply call them double cone vases, not sure wether there´s something like an offical
name for this design or not.
Generally they are rather hard to pin down since many german glassworks had something similar
within their range.
They simply vary by their width, the angle of the two halves and the point where they meet.
Friedrich, Zwiesel, WMF, Füger & Taube, Marsberger Glas, Hirschberg and surely others as well made
single coloured examples:

There must be a Friedrich vase in one of my boxes,
whose shape is almost identical with the Zwiesel one, but unfortunately I´ve lost the picture of it...
Then there´s cased examples, which I´ve so far only seen from Gralglas (Habermeier) and Ingrid.
Sorry no picture of a Habermeier vase available - for those, who have the Gralglas book: shape F112
and shape F196 (two versions). The latter are cased ones for sure, but the diameter of the waist is
only slightly smaller than their base and top. Since they were meant to ´speak by their shape´ I tend
to assume the 50´s Habermeier shapes weren´t decorated with inclusions and bubbles, which seems
a later decoration technique anyway. Just a hunch though...
Two different Ingrid shapes are these:

Zwiesel, Gral or Hessenglas.
The moral of the story? It´s a minefield - like always!!!
