Soldering your own posts can open you up to a whole new set of designs and creations. In this step-by-step guide, I will show you how to set up your soldering station, where to aim the flame, plus, give you tips on how to remove the extra solder during the finishing step. For this project I have used a standard double notched earring post and a small heart blank.
You can find the materials & supplies list at the end of this article.
Step 1: Prepping the Pieces
TipAfter sanding do not touch that area. At this point I transfer small pieces between stations using tweezers.
Step 2: Soldering Set-up
TipIf I were to place the jaws lower down on the post, it wouldn't allow the post to get hot enough to help the solder flow. Too high and I would be exposing the fragile post.
Step 3: Applying the Flux
TipEverybody has a preference when it comes to flux so we keep a paste and a spray in our jewelry studio at all times. I like to use the paste on small pieces and the spray on large pieces. Flux can cause build-up on soldering boards if you use too much.
Step 4: The Flame
TipNotice where the solder piece is positioned relative to the flame. Solder flows toward the heat source. So, by having the solder on one side of the post and the flame on the opposite side, the solder will flow towards the flame and right into the join.
Step 5: Pickling
TipBefore dropping it into your pickle pot, let it cool down for several minutes. The bubbles created when dropping it straight into the pickle can actually pop the pieces apart.
Step 6: Finishing
TipThe post shown has the sterling silver (.925) mark on it. Make sure you don't remove this while finishing your piece. I use flat nose pliers to protect it when I'm finishing the piece.

Once you’ve mastered soldering posts onto blanks, have fun shopping at Halstead for a wide array of jewelry findings you’ll want to solder together in your next post creation! Remember, you can often alter charms by using wire cutters to remove the hanging loop and filing away any remaining burs. They make great posts!
