Porte-clef Excella
Porte-clefs publicitaire contenant 3 grains de café vitrifiés de la marque de café EXCELLA des années 1950/1960.
La vitrification est un procédé de transformation par solidification, ou par mélange avec un additif, d'un matériau en un solide amorphe* (*sans structure cristalline) semblable à du verre. C'est à dire qu'on inclut un ou des objet(s) dans un produit** transparent ressemblant à du verre (**de la résine coulée transparente par exemple). C'est en 1830, que le 1er polymère*** (***la nitrocellulose) est mis au point par Henri Braconnet (1780-1855). Dans les années 1950, la mode des objets vitrifiés, appelés aussi les "inclusions", est à son apogée. La décoration, la botanique, la publicité,... s'emparèrent de ce procédé qui figeait l'objet l'empêchant de vieillir et disparaître dans le temps.
Depuis, des collectionneurs d'inclusions sont à la recherche de ces objets figés, témoins du passé, comme ces 3 grains de cafés intactes depuis...
EXCELLA était une entreprise française créée en 1905 spécialisée dans la torréfaction du café. Cette entreprise fut rachetée en 1996 par United Coffee.
Ce porte-clefs est toujours fonctionnel.
Pour des clefs, pour l'inclusion ou pour remonter le temps grâce à ces 3 grains éternels !

Vitrification is a process of transformation by solidification, or by mixing with an additive, of a material into an amorphous solid* (*without crystalline structure) similar to glass. That is to say that one or more objects are included in a transparent product** resembling glass (**transparent cast resin for example).It was in 1830 that the first polymer*** (***nitrocellulose) was developed by Henri Braconnet (1780-1855). In the 1950s, the fashion for vitrified objects, also called "inclusions", was at its peak. Decoration, botany, advertising, ... seized this process which froze the object preventing it from aging and disappearing over time.
Since then, inclusion collectors have been looking for these frozen objects, witnesses of the past, like these 3 coffee beans intact since...
