How to anneal white gold. The answer may surprise you.

What is the difference between annealing white gold and yellow gold?

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

I will break this down into its simplest form for this example. Back in the day 14k and 18k yellow gold were 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. These days there are Continue reading How to anneal white gold, The answer may surprise you.

How to anneal sterling silver - 7 BASIC STEPS

Annealing is the term for softening metal so that it is malleable. The process involves heating the metal and then cooling it. Cooling the metal can be achieved through air cooling, quenching and sometimes both.

Sterling silver is heated to a dull red(900F). Let it lose its redness and then quench in cool water. (Presto you have soft metal). There are a few steps before you can heat the baby up.

The metal should be coated in a protective substance called a “Barrier Flux”. It is made up of boric acid and 91% isopropyl alcohol.

Many people use denatured alcohol. I discovered it’s toxic and the human body does not metabolize denatured alcohol. This means it doesn’t leave your body very easily once you have absorbed it. Kind of scary. That is why I recommend 91% isopropyl alcohol because it’s less dangerous.

The 91% isopropyl alcohol burns off nearly as well as denatured alcohol. I do not recommend the 70% isopropyl alcohol.

You can mix the boric and isopropyl solution 50/50 for a thicker solution. This will provide a nice thick coating for your metal. This is good for annealing. If you are soldering you can use 25% boric and 75% isopropyl alcohol.

Use a glass jar with a lid. I use an old pickle jar or you could use
