About the history of origin: "FLOWER POTS AS BUILDING BLOCKS The square ‘building block flower pots’ designed by Andries Copier date from the same period as the ball vase. They are made of graniver, a kind of pressed glass developed by the Glasfabriek Leerdam, patented by the factory in 1921. It was also called sand glass due to the granular structure. Since the material is both cheap and strong, while it furthermore could also easily be coloured, it was deemed very suitable for the production of tiles and flower pots. The first flower pots, primarily intended for cacti and succulents which at the time were very popular, were round and rest with cylindrical legs on a likewise round dish. The model currently in the window sill in the living room is the square version, which was formed two years later in 1929. The square variant has two rectangular thickenings and ditto deepenings so that the pots can be interlinked. That way one could decorate the window sill with a continuous series of flower pots, creating a 'strong decorative effect'. As explained in the brochure that recommended the square building block flower pots upon their introduction under the telling title ‘A find!’. " Will be sent by registered mail
