Description
Procédé de fabrication d'émeraude synthétique. La présente invention a pour objet un procédé pour l'obtention d'émeraude synthé tique qui, convenablement taillée et polie, imite l'émeraude naturelle.
Suivant ce procédé, on fond un mélange de silice, broyée ou pulvérisée, avec une ma tière propre à donner au produit la couleur de l'émeraude, de la glucine hydratée ou anhydre, de l'alumine également hydratée ou anhydre et des fondants; cette fusion peut se faire par exemple dans un four oxhydrique, oxyacétylénique ou électrique. On brise ensuite la matière obtenue et chauffe à nouveau les fragments de façon à les ramollir, puis les soumet à un pétrissage.
<I>Exemple:</I> On prend quatre-vingt-dix grammes de cristal de roche que l'on chauffe presqu'au rouge, et l'on soumet brusquement à un refroi dissement en le plongeant dans de l'eau froide, pour que de cette façon il soit plus cassant, et ensuite on triture et pulvérise.
Le cristal de roche ainsi pulvérisé est additionné d'une dissolution aqueuse contenant cinquante pour cent de nitrate de cuivre et une quantité moindre de nitrate d'urane. Cette composition peut être plus ou moins concen trée ou être employée en plus ou moins grande quantité, selon l'intensité de coloration que l'on désire obtenir.
On mélange au cristal de roche susmen tionné vingt grammes d'alumine hydratée, vingt grammes de glucine hydratée ou anhydre et, en qualité de fondants: trente grammes de carbonate de lithine ou de lithine caus tique; quinze grammes d'acide borique fondu, en poudre; et quatre grammes de borate de soude, fondu et pulvérisé.
Le mélange ainsi préparé est fondu dans un creuset, au four oxhydrique ou électrique à une température de mille six cents à mille neuf cents degrés centigrades.
Le produit de 1a fusion est divisé en morceaux et ceux-ci sont soumis à nouveau à l'action de la chaleur jusqu'à ce qu'on obtienne un degré de ramollissement ou de mollesse qui permette de pétrir ces morceaux pour donner lieu à la formation de nouvelles pièces du produit. Cette opération est faite à l'aide de pinces ou d'autres outils appro priés. L'effet de ce nouveau ramollissement du produit est qu'il acquiert un aspect par ticulier qui le rend incomparablement plus précieux et plus semblable à l'émeraude na turelle.
Il enlève au produit de la fusion le caractère connu sous le nom de masse dure, c'est-à-dire l'aspect vitreux; en outre le pro duit petit gagner en dureté et cri éclat. Cette opération petit même être répétée plusieurs fois.
Ce produit, une fois traité lapidairement par la taille et le polissage, acquiert un aspect identique à celui. des éniera.tides (le provenance naturelle.
Synthetic emerald manufacturing process. The present invention relates to a process for obtaining synthetic emerald which, suitably cut and polished, imitates natural emerald.
According to this process, a mixture of silica, crushed or pulverized, is melted with a material suitable for giving the product the color of emerald, hydrated or anhydrous glucine, also hydrated or anhydrous alumina and fluxes; this melting can be done for example in an oxyhydrogen, oxyacetylene or electric furnace. The material obtained is then broken up and the fragments again heated so as to soften them, and then subjected to kneading.
<I> Example: </I> Ninety grams of rock crystal are taken and heated almost to red, and suddenly cooled by immersing them in cold water , so that in this way it is more brittle, and then we triturate and pulverize.
To the rock crystal thus pulverized is added an aqueous solution containing fifty percent copper nitrate and a lesser quantity of uranium nitrate. This composition can be more or less concentrated or be used in greater or lesser amount, depending on the intensity of coloring that is desired.
Twenty grams of hydrated alumina, twenty grams of hydrated or anhydrous glucine and, as fluxes, are mixed with the aforementioned rock crystal: thirty grams of lithium carbonate or causative lithium; fifteen grams of molten boric acid, powder; and four grams of soda ash, melted and pulverized.
The mixture thus prepared is melted in a crucible, in an oxyhydrogen or electric furnace at a temperature of one thousand six hundred to one thousand nine hundred degrees centigrade.
The fusion product is divided into pieces and these are again subjected to the action of heat until a degree of softening or softness is obtained which allows these pieces to be kneaded to give rise to the mixture. formation of new parts of the product. This is done using pliers or other suitable tools. The effect of this new softening of the product is that it acquires a peculiar appearance which makes it incomparably more precious and more similar to natural emerald.
It removes from the product of fusion the character known by the name of hard mass, that is to say the glassy appearance; in addition, the product small gains in hardness and shine. This operation can even be repeated several times.
This product, when treated lapidarily by cutting and polishing, acquires an identical appearance to that. des eniera.tides (the natural origin.
