White gold

Is a chemical element called platinum. It is a pT in the periodic table. Its atomic number is 78, a precious and rare metal, but no trace of it was found in ancient civilizations. It was discovered in the 16th century in South America. Which is a Spanish word meaning small silver, and it is produced in Africa, as it is considered the most productive country with about 80% of the world production, and we will know a number of its advantages.

 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. This is because 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 quantities 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 protective glasses and gloves.

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 materials.

History of White Gold:

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