One of the problems is simple.
Early post-war off-hand production in Czechoslovakia, was heavily influenced either by Italy, or Scandinavia. If one looks at the 1954 Skrdlovice catalogue for example, there are pieces which, were it not for their images in that catalogue, would be difficult to place precisely. It is really only after 1955 or 56, when Emanuel Poche spear-headed the drive toward a more Czechoslovakian style, (for the most part because he was also in charge of the committee organising the country's Brussels Expo'58 submissions)that off-hand work became once more, identifiably Czechoslovakian. This was during the "de-Stalinisation" period, and as artistic production started to find itself less pressured into social realist conformity, so too design started to benefit from a less heavy-handed approach.There are a number of articles in CGR of the period, which discuss the problems faced by the Czechoslovakian glass industry, the need to keep producing items which satisfied customers in the more conservative markets, the need to develop new products that would be able to compete on their own merits, with the production of Scandinavian, and Italian manufacturers.
The images of current Chribska production show many pieces which have been in production for several decades. It still sells.
