Soldering the parts together

: Soldering jewelry: workshop This instructable is based on a jewelry workshop I followed 1,5 years ago. My mother came across an advertisement for a youth jewelry workshop. These are the pictures taken directly after they were made, the intro picture is pandor bracelets from .When all the parts have been bent, it's time to solder them together.For the soldering, I used silver solder and a burner. After the soldering I used vitriol.There are three types of the solder: Hard, middle and soft. Hard solder has the highest melting point: around 740 degrees Celsius. Middle solder has a melting pandora charms outlet point of around 680 degrees and soft solder has a melting point of around 650 degrees.These different types of solder are useful when you pandora charms on sale need to solder multiple parts on one place. I used this to make the ring: I started by making the butterfly shape. I soldered the two halves together using hard solder and when soldering the butterfly to the ring, I used soft solder. Because the soft solder has a lower melting point, the connection made with the hard solder won't be broken when heating this part again.When a part only needs to be soldered once, middle or hard solder is recommendable for a strong connection.To solder the parts together: Carefully place a piece of solder on the connection you want to make. Since the pieces are quite small, it's pandora uk sale easiest to use tweezers. Take the burner and heat the pandora charms sale clearance part you want to solder. When it's hot enough, the solder will melt. When it does, you can stop heating it. What might cause a bit of pandora outlet trouble here, is the flame from the burner actually blowing away the solder. If this happens, try heating it with a different angle.Once you have soldered all your connections, place the piece of jewelry in a small bowl (large enough for the piece of jewelry of course) of vitriol (10 % sulfuric acid, 90 % water). This will dissolve the remains of the soldering.Make sure not to get any iron in your vitriol   if your jewelry piece is in there, it will change the colour of your piece. When you pandora outlet leave something made of iron in vitriol for a while, it will dissolve.
