No século XIX, a fabricação de espelhos deu um salto importante com o uso do nitrato de prata. A técnica foi desenvolvida em 1835 pelo químico Justus von Liebig, que descobriu como fixar uma fina camada de prata no vidro através de uma reação química. 🧪 Esse método substituiu o uso de mercúrio, que era tóxico, e tornou os espelhos mais seguros, duráveis e acessíveis. A base desse processo continua sendo usada até hoje na produção moderna de espelhos. 🪞
