INTRODUCTION 
The variety of glass produced in the period 1905 to 1925 in the area of the Austro-Hun- 
garian Monarchy and the countries which succeeded it seems virtually inexhaustible. 
For this reason, if for no other, it will probably continue to have no uniform stylistic des- 
ignation. The innumerable variations of shape, technique and decoration ränge from 
thin-walled, undecorated blown glass to solid, deep-cut crystal glass, from distinctive 
decorative seams with several overiays to multi-coloured etched surfaces, from continu- 
ous jet black to delicate line drawings, from opaque painting to brilliant vitrified enamels, 
from under-cutting to delicate figure engraving. The effect of colour in varying light 
which appears to make many glass vessels change continuously can no more be cap- 
tured at one glance than it can in a single illustration. Though gold shines in reflected 
light, in transmitted light it gives way to the inherent colour of the glass itself; though 
reflected light emphasises the shape of dark coloured glass, red glass glows in focused 
light and in the coloured shadow of transmitted light. 
Exquisite vases as individual pieces contrast with cut glass table Services. In sets the 
central glass vessel dominates the smaller pieces: punch sets, liqueur Services, beer 
Services, etc.
