REAL LAVA vs Fireproof GLASS: Will It Break

Amazing satisfying EXPERIMENT with REAL LAVA (FROM a VOLCANO!) and the strongest FIREPROOF GLASS. We’ve tested regular window glass and fire-resistant glass against one of the hottest substances on Earth! ☑ What is a FIREPROOF GLASS? It is a multi-layered glass, where the sheets of glass are connected by means of intermediate layers made of fire-resistant gel, which expands under high temperature. During a fire, when the temperature rises to 100°C (212 °F), the gel layers expand forming a hard, non-transparent layer, which temporarily prevents fire propagation.
