This video is about how to annealing white gold with a torch.
What is the difference between annealing white gold and yellow gold?
Here is a TOOL LIST for the jewelers torch. [ Ссылка ]

The answer may surprise you because the difference is as simple as what type of allow is used. 

I will break this down into its simplest form for this example. Back in the day 14k and 18k yellow gold was alloyed with copper to make a wearable and workable metal.

14k yellow gold was 58.5 parts 24k gold mixed with 41.5 parts copper. 

18k yellow gold was 75.5 parts 24k gold mixed with 24.5 parts copper.

I am using copper as an example. Now days there are many secret allows created for different types of metal working. Some are for casting, some are for rolling and so on. They may have element of copper and other metals mixed together to work better under different conditions. Just keep it in mind for down the road. 

14k and 18k white gold is alloyed with nickel to make a wearable and workable metal.

14k white gold was 58.5 parts 24k gold mixed with 41.5 parts nickel.

18k white gold was 75.5 parts 24k gold mixed with 24.5 parts nickel. 

Once again, I am using nickel as an example. Now days there are many secret allows created for different types of metal working. Some are for casting, some are for rolling and so on. They may have element of copper and other metals mixed together to work better under different conditions.

Yellow and white gold are going to have on thing in common and that is the amount of gold in each, whether its 14k or 18k. 

The big difference when it come to annealing is what is in the alloy. A copper alloy can be heated and quenched while hot. It will then be annealed or the metal will be softened making it workable.

I will include a link to my torch set up and tool list. I am using propane and oxygen mixture. Use a large flame with a feathery end. Using a sharp hot flame will only melt your project.
