Features of Platinum Element

Platinum is much stronger than iron metal, and its elasticity is as gold’s elasticity.
It never rusts and does not change color if exposed to air. The reason is that platinum does not react with oxygen gas, so it is called noble metal.
It does not affect any acid used to dissolve other elements.
Its value is double the value of yellow gold.
Do not oxidize at high temperatures.
Slow expansion if exposed to heating.
Slow melting in the water of fire.
We need to dissolve large amounts into high temperature resistant furnaces due to the high melting point of platinum. The small quantities are mixed with the goldsmith using an oxalic acid with the use of glasses and gloves for prevention.

History of White Gold

White gold first appeared in 1557 by the Italian scientist Julius Scaliger. In 1750 the Spaniards discovered plenty of platinum, but its value was cheap at the time. But when scientists and specialists discovered its many benefits, it was used in all areas of life and spread very quickly. Its demand has risen and prices have risen.

Manufacture of slabs and thin wires.
It enters the field of transformer located in automobile exhaust.
His use in medical fields, such as dental surgery.
It enters the jewelry industry, such as necklaces, watches and earrings, to distinguish it with strength.
Used in scientific experiments.

Types of white gold

White gold is classified into two types. The first type is gold and different metals, such as silver, palladium and copper, while the latter type is made of pure platinum itself, without adding any other material.

Distinguish between pure white gold and platinum

We can distinguish between them through a test called zero test, which is a piece of white gold and scratched, if scratched easily is white gold, and the second method is to heat a piece of metal and let it cool until it turns to a dark color is white gold. It is a piece of platinum, and women have bought this metal to match the fashion or because of its attractiveness and beauty, and also the reason for the taste of every woman.
