"Cermák is famous for his modelled visions in enriched, melted glass. His use of surreal elements is particularly striking. He creates models by chopping, trimming and grinding boards with coarse tools, achieving a rare rawness of expression, making his work highly tactile and obtaining striking nuances of colour. He is also changing the way he uses colour, combining glass of complementary colours to create tension and contrasts."
