The glass industry was one of the most important export industries in the interwar Czechoslovakia. Export focus of the Czechoslovak glass industry influenced significantly its economic development and the social status of glassmakers, especially ordinary workers.
At the end of the twenties, in the years of economic boom, the Czechoslovakian glass production was dependent on sales abroad up 80%. Dependence on trade with foreign countries did glass industry very vulnerable, because this industry subjected easily to economic changes in foreign markets.
This handicap is mainly reflected in the first half of the thirties, in a time of economic crisis, when export orientation was the main cause of the decline of glass production. During this period, glassmaking was one of the most affected sectors of Czechoslovak industry.
The consequences of poor economic conditions in the first half of the thirties were reflected mainly in the Jablonec nad Nisou region. This region was one of the most important areas of glass production in Czechoslovakia between the years 1918-1938.
