The age-old technique allows a simple sheet of flat glass to be elevated to an elaborate masterpiece, with a surface that can be used as a playground for designers. For Porta, Velčovský worked with handprints, although anything can be used — from rollers to paintbrushes, ceramic beads and rope, to create patterns and motifs on the thick layers of a special sand-like heat-resistant powder.
Porta was introduced as a monumental installation on Milan Design Week 2024, where it received the 2024 Fuorisalone Award.
