Gold Blob
Purity: 42%-75% 10-18 karats
Minimum Order: 25 kg
Gold blobs are an amalgam of gold, silver, copper, and dirt combined. Gold blobs normally have a range of 41% -75%. The amount of silver and copper in the gold blob can vary, but they are usually in lesser amounts. Other elements that may be present in gold include platinum, palladium, and rhodium. These are rarer than silver and copper and are only found in quantity in most gold blobs. Below is The Chemical Composition of the 41% Gold Blob.
THE CHEMICAL COMPOSITION OF GOLD BLOB
| ELEMENT | ATOMIC SYMBOL | PERCENTAGE BY MASS |
| Gold | Au | 41.00% |
| Silver | Ag | 28.57% |
| Copper | Cu | 19.44% |
| Other Elements | 11.00% |
The presence of other elements in gold blobs can affect their color and purity. For example, a gold blob with more silver will be whiter than a gold tone with less silver. Similarly, the gold blob will be red in color if there is more copper present.

INDUSTRIAL USE
Gold is used in many industries due to:
Its high electrical conductivity,
Withstanding high temperatures and heat,
Resisting corrosion and tarnish, and
Malleability to be molded easily.
| INDUSTRY | APPLICATION | |
| Jewelry | Gold is the most preferred to design jewelry. It is prized for its beauty, durability, and rarity. | |
| Electronics | Gold is used in various electronic applications, such as circuit boards, connectors, and contacts. It is a good conductor of electricity and heat and also corrosion-resistant. | |
| Dentistry | In dentistry, gold is preferably used in dental fillings, crowns, and bridges. It is a biocompatible metal that is well-tolerated by the body. | |
| Medicine | Gold is used in some medications, such as Myochrysine, which treats rheumatoid arthritis. It is also used in some topical treatments for psoriasis and other skin conditions. | |
| Aerospace | Gold is used in some aerospace applications, such as the windshields of jets and the visors of astronauts’ helmets. It is a good reflector of infrared radiation, which makes it helpful in shielding against heat. | |
