What the Flux?? What is Flux, and Why is it So Important?

Hey there, jewelry makers! If you're new to soldering silver, you may have heard the term "flux" thrown around. But what exactly is flux, and why is it so important to the soldering process?

Simply put, flux is a substance that is used to clean and protect the metal during soldering. When you heat metal to a high temperature, it can oxidize and form a layer of tarnish or scale on the surface. This can interfere with the flow of solder and weaken the joint. Flux works to remove this oxidation and prevent new oxidation from forming, creating a clean and smooth surface for the solder to adhere to.

There are several types of flux available for soldering silver, including liquid flux, spray flux, and paste flux. Liquid flux is the most common type and is applied directly to the joint using a brush or dropper. Spray flux is a more convenient option for large or complex pieces, as it can be easily applied with a spray bottle. Paste flux is a thicker consistency and is applied to the joint with a brush or applicator.

When choosing a flux, it's important to select one that is appropriate for the type of solder you're using and the level of heat you'll be applying. Some fluxes are specifically designed for use with silver, while others are more versatile and can be used with a variety of metals.

So, whether you're soldering a simple ring or a complex pendant, don't forget the importance of flux in creating a strong and clean joint. With the right flux and a little bit of practice, you'll be well on your way to creating beautiful and durable pieces of jewelry.
