Gold is an extraordinary precious metal with a long history, which is nicknamed “the King of Metals”. This material is widely used for jewelry, but also for space travel, dentistry and electronic components. Approximately 80% of our gold on earth is used for jewelry. That is quite a lot!
This material is connected to the energy of our sun and is a very good conductor of energies and high frequencies. It opens the crown chakra and helps you gain wisdom from the universe and your higher self. It is also a good energetic protector, which is why talismans, amulets and protective symbols are often made of this remarkable metal.
Ancient Egyptian priestesses used this pure material to channel healing energies. But coins and the “death masks” of the pharaohs are also made of it. Not surprisingly, this is a popular material. Alchemists, for example, were looking for years for the Philospher’s Stone in order to convert other matter into gold.
This metal itself is a heavy but soft metal that does not corrode. Because it is so soft ( hardly malleable ) it is alloyed with other metals to make it harder. The amount of gold in the alloy is expressed in karats. The most common is 14K, 18K and 22K.
With 3D printing it is only possible to get 14K and 18K.
Unfortunately our Dutch language has not made any difference between the two different carats (in English they have Karat & Carat).
Carat represents a unit of mass (such as gram, kilogram, etc.). This carat is mainly used for gemstones.
1 Carat equals 0.2 grams and 1 gram equals 5 carats.
The other Karat represents a content. This Karat is mainly used for alloys of precious metals. The contents are divided into 24 parts. 24 Karat’s means that 24/24 part is gold, in this case 100% pure gold. 18K means that 18/24 is part gold, so 75% gold and 25% other metals.
Then there are different colors, such as white gold and rose gold. These colors are the result of the different metals used in the alloy. As explained above, other metals are often added to the alloy to make it harder, otherwise it is too soft and almost malleable.
The most commonly used additiv metals are silver, copper, zinc and sometimes nickel or palladium. Silver, zinc, nickel and palladium are naturally white metallic and copper is naturally reddish. Depending on the ratio with the (pure) gold, the final metal gets its specific color.
For example, 14K gold contains copper and silver (usually a little more copper with a little zinc) to give it its yellow color.
14K rose gold, for example, contains a lot more copper with a very small amount of silver and zinc, so you get a much warmer color.
14K white gold, for example, contains much more silver than copper with zinc and nickel (or palladium), which gives it a much whiter color.
The exact proportions of the gold depend on the supplier or goldsmith, but the percentage of gold is fixed.
