Titanium
Titanium is used to make gold harder. They often use gold mixed with titanium in jewelry to make it harder.
Because it is very rare, more valuable than gold, and it is hard enough that it won't wear down.
because they are hard and expensive
Gold is naturally a soft metal due to its atomic structure, but alloying it with other metals such as copper or silver can increase its hardness. The addition of these metals forms a stronger crystalline structure, making gold suitable for jewelry making. The higher the percentage of other metals in the alloy, the harder the gold will be.
The term "24 karats" indicates that the jewelry is made from pure gold, with no other metals mixed in. Pure gold is too soft for most jewelry applications, so it is often alloyed with other metals to increase its durability.
Gold is relatively soft compared to other metals. Its hardness is measured at around 2.5 to 3 on the Mohs scale, which is a scale used to determine the hardness of minerals. This softness makes gold easy to shape and mold into different forms.
because it is an harding agent
Finding gold is hard without technology but, the best places to find gold are in, lakes Rivers, creeks ,and jewelry shops.
I guess technically there is only yellow gold when thinking of gold in the pure form. Alloys are mixed with yellow gold to produce white gold. Jewelry manufacturers purchase bricks of yellow gold which are 24ct. 24ct is the highest carat you can cast gold in. Any higher of a carat and the gold is too soft. The 24ct gold is then melted and turned into tiny pebbles. These pebbles are mixed with different alloys just before being cast into the jewelry mold. White gold is created by mixing nickel with yellow gold. Rose gold is created by mixing copper with yellow gold.
because its really low in the rective series and is hard to tarnish.
Yes, it is homogeneous mixture of Gold or silver or Gold or Copper. Since, pure gold is very soft, it cannot be used to make jewelery and thus with 22 parts of gold 2 parts of silver or copper are mixed to make it hard.
The gold came form space originally. Because of two or more stars smash together and created a really hard stuff called gold. There has to be enough heat, though. The gold came form space originally.
