my final project consists of a machine to analyze the degree of purity of precious metals such as gold and silver.

I am currently taking the references of the principle of Archimedes to be able to reference by density the type of material.

I am interested in being able to contribute with the artisan jewelry sector in my country, and to be able to develop this machine, which is accessible to small jewelery shops, and in this way improve the law of the metals of the final product.

 

Equipment to determine the type of metal, according to the Archimedes method.

PRINCIPLE OF ARCHIMEDES: Every body submerged in a fluid, suffers a push or vertical force upwards equal to the weight of the fluid dislodged.

First we weigh the metal that is going to be analyzed, then the same metal is immersed in the container full of water, achieving a displacement of the water towards the plate of the scale.

The formula of Density = mass on volume is made.

The result is compared with the table of metal densities, and it gives us the type of metal.
