How to Solder Glass PendantsApril 18, 2013

Our original tutorial on “How to solder jewelry with Simply Swank Tools” has been very popular. Unfortunately, we no longer are able to supply several of the supplies mentioned in the original post. I have attempted, here, to provide information on currently available products, and to answer some questions.

About Soldering

Solder is a confusing topic. There are two completely different soldering methods used in jewelry making, yet people rarely explain which type they’re talking about – much the way people say they spent the weekend simply “at the lake.” (If they are your friends, you do know which lake … and hopefully this post will help you make friends with solder!)

Solder is a metal alloy that is melted to connect or coat metal pieces. Soldering is the act of melting and applying solder.

The two soldering methods are:

  1. Soldering with a torch. Often called hard soldering, brazing or silver soldering, although copper, brass, gold and other metals can be torch soldered. There are different grades of hard solder (which melt at different temperatures, and just to confuse things further, are called easy/soft, medium and hard). There are also different solder formulas to match the color of various metals. This post talks about copper wire solder, which is meant for torch soldering.
  2. Soldering with a soldering iron. This is often referred to as soft soldering, and is used with base metals (like pewter) and plated metals. This is actually ‘tinning”, which means adding a layer of solder to a metal base. The solder is made mostly of tin and has a (relatively) low melting temperature. Soft solder is pewter or silver colored. Never use a soldering iron with precious metal jewelry: it will ruin the jewelry.

Therefore, if jewelry is made of silver or gold, it has to be torch soldered. Successful soldering requires heating the metal pieces, not just melting the solder, so if the piece is very large or thick, it’s probably torch soldered as well.

First off, not all soldering irons are created equal. There are many varieties on the market and most were not designed for jewelry making. The two most important things to look for are tip style and wattage. We recommend a minimum of 60-watt soldering iron with a chisel-tip. The pointy tip irons are designed for tiny electronics like circuit boards and are of little use for jewelry, other than sealing jump rings. Lower than 60 watts might not heat up enough. The 60w Hakko soldering iron meets both requirements! The 100 watt Choice Iron and Rheostat combination provides greater control over temperature.

Soldering iron tip comparison

 

The iron on the left has a pointy tip (not recommended). The iron on the right has the recommended chisel tip, but needs to be cleaned! Soldering is difficult when the tip is black and crusty. Try using the wet sponge to clean the heated iron. If you can’t clean it any other way, let the iron cool and then gently sand off the gunk.

Next, the solder itself. It is important to use lead-free solid-core solder. Avoid solders that have rosin or acid cores. Rings & Things sells Choice, SILVERGLEEM, and Staybrite silver solder. All 3 work great with soldering irons; Staybrite is more expensive because of its higher silver content and included flux.

Third, flux. All solder requires flux in order to melt and flow. LA-CO Brite flux is a 6oz package, and is designed to be dripped or brushed onto your project.

Here is a condensed version of the process:

Preparing to Solder a Glass Pendant

Prepare your work area. Remove extraneous (burnable or meltable) items from the immediate area. I like to use a cookie sheet with a Non-Stick Craft Sheet on top. The craft sheet allows for easy clean-up of the drips and spills of solder that will inevitably occur.

Taping the edges

 

Copper tape creates the metal base needed for the solder to flow onto.

Sandwich images between 2 pieces of glass and wrap edges with copper foil tape, peeling off the tape as you go. If you plan to add a bail or jump ring, overlap the ends of the foil tape where you are adding the hardware. Fold the tape over from the edges to the front and back of the glass, being careful of the corners (think of it like wrapping a gift). Burnish smooth (a sharpie pen works well for burnishing). Clean with alcohol to remove any oils from your fingers – a clean surface is the best soldering surface!

Shaping the solder coil into a snake makes it easier to feed onto your soldering iron.

Solder “snaked” for ease of application, Stand ready for use.

Prepare the Soldering Iron stand by adding a few tablespoons of water to the sponge in the reservoir.

retinning-the-tip-300x200.jpg

Retinning the tip

If this is your first time using the iron, you will want to “tin” the tip the first time you heat it up and always maintain that layer of solder across the tip. By tinning the tip, you prevent the iron coating from oxidizing, which is a real problem when you have hot iron tips. Oxidation can corrode your tips forcing you to replace them more often, and the hotter your iron the faster they will oxidize. Tip tinning creates a layer of solder between the air and the iron, keeping oxygen at bay.

Plug in the soldering iron and allow it to heat up for a couple minutes. Touch the tip to the damp sponge. The iron is hot enough if the sponge steams a bit when you do this. Holding the solder in one hand and the iron in the other, briefly touch the solder to both sides of the tip. You may have to “rub” the solder onto the iron to start it flowing.

Now that your tip is properly tinned, you can start soldering. Try to solder immediately after tinning the tip, the sooner the better. Tinning improves conductivity and makes soldering easier, as well as quicker, which is a good thing. Periodically while you are working , (when the solder doesn’t seem to be flowing well), clean off any globs of solder on the sponge and re-tin the tip. Keeping the tip clean is important but constantly wiping it on a wet sponge will lower the iron temperature, and can cause early tip failure. Properly cleaned tips are bright and shiny.

Keep the iron in the stand whenever you are not actually soldering with it. Unplug the iron whenever you are working on another portion of the project for more than a few minutes. This is not only a good safety measure, but it will also extend the life of your soldering iron. When you are not using your soldering iron, you should keep a layer of solder on the tip, so before putting your iron in storage, apply a fresh layer of solder to the tip to prevent it from corroding. If you will not be using your iron for an extended period of time, you may want to store it (after it has fully cooled) in a zipper type bag to protect it further from corrosion and humidity.

Adding solder to the tape

Soldering a Glass Pendant

Apply flux to the copper tape. Touch your hot soldering iron to the solder to pick up a blob, and run the iron over the copper tape. Repeat. Repeat. (Some people melt the solder onto the tip of the iron and transfer it to the piece. I find I have more control by applying the solder directly from the roll to the tape.) Often you can pull the solder from the edges of the pieces to the front and back taped portions. Completely cover the copper tape with solder. If it looks lumpy, run the iron across the bumps to remelt the solder and smooth it out. Be sure to clean your soldering iron’s tip frequently. If the solder isn’t flowing, either the tip is dirty, your piece is dirty, you need more flux or you aren’t heating the piece sufficiently. Clips, clothespins or a third hand are all helpful tools for holding your piece while protecting your fingers.

This piece is being held in place with binder clips, allowing me to hold the spool of solder in one hand, and the iron in the other.

Here I am holding a piece steady with bent chain nose pliers. Since flux can damage tools, and you may drip solder onto them, dedicate an inexpensive or already damaged pair for use in soldering.

Using hemostat to hold the jump ring in place while melting the solder blob with the iron.

Add a blob of solder to the point where you’d like to attach your jump ring. Apply flux to your jump ring. Use pliers or a hemostat to hold the jump ring on the blob, and reheat the blob with the iron to secure it in place (watch out: the blob will melt quickly, and the jump ring will sink into it. Do not maintain the heat on the blob or the jump ring, or it will all melt together into a mess). Clean off any extra flux with window cleaner or rubbing alcohol, file rough edges, buff with a polishing cloth, and you’re done!

Beaded Spider Tutorial

0921112005.jpg
Here are the simple steps to create a large (about 3-4 inches square) beaded spider. The beads used are for the spider shown. The size of beads can be adjusted to fit the size of spider you want to create. These are fun to create!
0921111848.jpg
Step One: Find a large bead for the spider body and a slightly smaller one for the head. Here I'm using a 16mm round bead for the body and a 10mm round bead for the head. I also added a 3mm Swarvoski crystal and a crystal rondelle spacer to the back of the body to just add a little more sparkle. You could also add bead caps and a rondelle in the center of the spider if you desired. Place the beads on a flat head pin and twist the end down like a little coil with a pair of jeweler pliers or needle-nose pliers (use the very tip).
0921111849.jpg
Step Two: Cut 4 long pieces of wire, about 7 inches long each. Use wire that can easily bend and twist. I use from 24-28 gauge and different colors depending on the spider color. Fold the four wires in the middle, creating eight legs.
0921111850.jpg
Step Three: Place the wires between the head and body beads and twist them in the under side. Thinner wire can be twisted once, but thicker wire will only be able to be "pointed" in the opposite direction...without any actual twists. That is the case with this spider, here is what the wire looks like at the underside of the spider.
0921111942.jpg
Step Four: Plan your beads for the legs. Always start with seed beads because the legs will begin by hugging the body and need to have small beads to start. Add larger beads or combination of beads to mimic "joints" in the legs, there will be two of these areas. Then end with seed beads and bugle beads for long slender portions of the legs. For this spider I've used this sequence of beads for front/back legs: 5 seed beads pink, 4mm flat round pink, 6 mm round ivory pearl, 4mm flat round pink, seed bead, bugle bead, seed bead, 5mm rice bead, seed bead, bugle bead, seed bead, bugle bead, seed bead, bugle bead, seed bead, seed bead. The center legs have one less bugle bead and seed bead than the front and back legs..this is optional as all eight legs could be the same.
0921111953.jpg
0921111958.jpg
Step Five: Place the beads on the wire. Cut the end of the wire until you have about 1" of extra wire left. Twist the end like a spiral until it touches the last seed bead placed. Repeat this to complete all eight legs.
0921112003.jpg
Step Six. The spider is finished. You can play around with the placement of legs until you have a realistic pose. I start by pulling all eight legs straight up and putting the spider body flat on the table with the top facing up. Then I bring the middle legs down bending at the "joints" and having the legs at a straight angle out from the body. The front and back legs are done in a similiar manner but are pointed towards the front and back instead of the side. (Note: This spider would hang from it's "head" because that is the coil end of the head pin...if you wanted it to hang down from it's "tail" the head pin would start at the head and be coiled at the tail instead.)
0921112006.jpg
Here is how the spider looks underneath when finished.
0921112025.jpg
So, go find some beads...and wire...and one flat head pin (or use a piece of wire and coil both and head/tail ends)...and create a beaded spider. Have some fun!
