\u00bfC\u00f3mo se consegu\u00eda que los barcos de madera<\/p>\n
navegaran durante semanas sin hundirse por las filtraciones de agua?<\/p>\n
La respuesta estaba en una t\u00e9cnica tan antigua como la propia navegaci\u00f3n: el\u00a0calafateado.<\/p>\n
Durante milenios, mantener una embarcaci\u00f3n a flote dependi\u00f3 de un detalle casi invisible: impedir que el agua penetrara entre las tablas del casco. Para conseguirlo se desarroll\u00f3 el arte del calafateado, una t\u00e9cnica que empleaba sustancias impermeabilizantes de naturaleza pegajosa y densa. Entre ellas se encontraban productos de origen vegetal, como la pez o la brea obtenidas de resinas de con\u00edferas, y otros de origen mineral, como los betunes naturales derivados del petr\u00f3leo.<\/p>\n
