Reemplazar el \u00edndigo por la f\u00e9cula azul proveniente del pastel de los tintoreros<\/h2>\n\n\n\n

El 21 de noviembre de 1806, Napole\u00f3n hab\u00eda decretado el bloqueo continental, medida adoptada para privar a Inglaterra de toda comunicaci\u00f3n con el continente. Por esta raz\u00f3n, algunos productos faltaban, como el \u00edndigo, una variedad de colorante azul. El gobierno propuso de sustituirlo con la f\u00e9cula azul proveniente del pastel. El colorante azul se extra\u00eda a partir de las hojas. En 1811, el gobierno lanz\u00f3 un concurso para desarrollar la cultura del pastel. Nic\u00e9phore har\u00e1 el comentario :<\/p>\n\n\n\n

\u00ab [ \u2026] se trataba de extraer el \u00edndigo del pastel. Deber\u00edamos estar deseosos de participar de investigaciones cuyo resultado parec\u00eda estar ligado a la prosperidad del comercio y de las artes industriales.<\/em>
Las que llevamos a cabo fueron extensas, pero para nada infructuosas, en relaci\u00f3n a lo que m\u00e1s nos interesaba ; porque las muestras de esta materia colorante que enviamos de las oficinas de la sub.-prefectura al Ministerio del Interior, nos valieron los est\u00edmulos mas sol\u00edcitos y halag\u00fce\u00f1os.<\/em> \u00bb<\/p>\n\n\n

El fin era el de mejorar el rendimiento de la producci\u00f3n del colorante. Los hermanos Ni\u00e9pce transmiten al ministerio del interior muestras de la f\u00e9cula colorante que lograron extraer de las hojas de la planta, as\u00ed como un informe explicando como obtuvieron esta materia colorante.<\/p>\n\n\n\n

Le ruego les anuncie que los transmito a la comisi\u00f3n encargada del examen de todas aquellas otras que de la misma naturaleza han sido hechas en distintos lugares, y de indicar lo que es mas propio para establecer completamente la teor\u00eda de la fabricaci\u00f3n del \u00edndigo pastel, y para perfeccionar su pr\u00e1ctica.<\/em> \u00bb

El concurso instaurado por el gobierno no aport\u00f3 resultados prometedores. En 1813, este decidi\u00f3, sin embargo, de relanzar el inter\u00e9s por la cultura del pastel y de la extracci\u00f3n del \u00edndigo, otorgando primas : tres a cinco francos seg\u00fan la calidad y a condici\u00f3n de producir al menos cincuenta kilogramos de azul por a\u00f1o. El 24 de abril de 1813, el prefecto en persona incit\u00f3 a los hermanos Ni\u00e9pce para volver a trabajar sobre este proyecto. El cultivo del pastel retom\u00f3 con toda intensidad en Saint-Loup de Varennes. Cincuenta y seis a\u00f1os mas tarde, en 1867, el historiador Fouque testimoni\u00f3 : \u00ab [\u2026] el cultivo del Pastel-\u00cdndigo, Nosotros mismos lo vimos, ha dejado numerosas huellas en lo que constitu\u00eda en otra \u00e9poca el bello dominio Ni\u00e9pce, en Gras, comuna de Saint Loup de Varennes. Los jardines de la residencia de esta familia, los campos, incluso las zanjas de la gran ruta, sobre una extensi\u00f3n de varios kil\u00f3metros, contienen plantas de pastel [\u2026] que se reproducen naturalmente sin cultivo, desde mas de un medio siglo.<\/em> \u00bb<\/p>\n\n\n\n

El a\u00f1o 1812 hab\u00eda sonado la decadencia del Imperio. El Imperio se desmoronaba poni\u00e9ndole fin al bloqueo. El cultivo del pastel se volvi\u00f3 in\u00fatil.<\/p>\n","protected":false},"excerpt":{"rendered":"
