\"\"On se demande souvent que deviennent les d\u00e9bris d’Or<\/a> qui sont rachet\u00e9s par les bijoutiers ? Que peuvent-ils bien en faire ?<\/span> Pourtant la r\u00e9ponse est tr\u00e8s simple : les d\u00e9bris achet\u00e9s ainsi que les bijoux sont r\u00e9unis par kilo d’Or<\/a> pour pouvoir servir \u00e0 ce qu’on appelle une fonte d’Or<\/a><\/strong>. En effet, pour cela, le bijoutier doit d\u00e9tenir au minimum 1 kilo d’Or<\/a>. Par la suite, le bijoutier place cet Or<\/a> dans un creus\u00e9 en y rajoutant, la plupart du temps, une poudre blanche pour nettoyer et optimiser le fonctionnement de la fonte.<\/span> L’\u00e9tape suivante sera la fonte de l’Or<\/a>. Pour cela, il faut placer le creus\u00e9 sur un appareil avec un chalumeau point\u00e9 sur lui. Pendant que le chalumeau agit, une lingoti\u00e8re est chauff\u00e9e \u00e9galement, sans quoi un choc thermique pourrait avoir lieu au moment de la coul\u00e9e de l’Or<\/a>.<\/span> L’Or<\/a> ne sera vers\u00e9 dans la lingoti\u00e8re qu’une fois qu’il aura atteint son point de fusion (1 064.18 \u00b0C). C’est \u00e0 ce moment l\u00e0 que l’Or<\/a> vers\u00e9 prendra la forme d\u2019un lingot<\/a>.<\/span> En g\u00e9n\u00e9ral, le bijoutier, proc\u00e8de \u00e0 un pr\u00e9l\u00e8vement de quelques grammes d’Or<\/a> au moment de la mise en fusion de l’Or<\/a> afin d’analyser la teneur en Or<\/a> fin du lingot. Pour cela, il devra utiliser un appareil qu’on appelle un spectrom\u00e8tre. Il est rare que ce test ne donne pas de r\u00e9sultats concluants.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
