129 hand-blown crystal tubes
The installation for the Czech National Pavilion is based on Signature Design – Crystal Grid, which consists of 129 hand-blown crystal tubes arranged in geometric grids. Perpendicular lines and minimalist components create a regular structure that emphasizes the purity and clarity of the crystal.
Visitors to the Czech national restaurant will be able to admire the spectacular crystal installation with dynamic lighting scenes at happy hour. The whole installation will also include Raw Crystal components, another Signature Design.
Crystal Grid represents the pure harmony of geometry. Minimalism is very popular in Japan, which is why we deliberately chose this design for the Czech pavilion together with the architects. It combines simplicity of form with the precision of handmade and celebrates Czech craftsmanship in its purest form. However, thanks to dynamic lighting scenes, it goes beyond the traditional concept and shows how innovation and technology enrich the art of glassmaking.
