Sterling Silver Tips

Tips For Using Sterling Silver

 

Sterling Silver Flat Sheet

Sterling Silver sheet is flat and soft temper. 

Sterling Silver Sheet is available in pieces 6” in width up to 24” lengths. 

We will try to accommodate your required size but one dimension must be 6” and the other in increments 1” or larger.

Silver Solder 

Silver Solder in easy, extra easy, medium and hard flows. It is not advisable to combine standard silver solders with Argentium® silver.

Silver Flat Sheet Solder is supplied in 1/2 T.O. (1” x 4” flat sheet)   

Silver Round Wire Solder is supplied in a 10 foot minimum.  (1 T.O. = 20ft.)

Silver Paste Solder is supplied in Easy, Medium and Hard flow

Silver Solder is Cadmium Free

Soldering: 

  • Cleaning: Make sure your piece is clean before soldering; solder won’t flow on a dirty or greasy surface.  You may use a de-greasing detergent or cleaner and scrub with an abrasive pad or pumice powder, removing all dirt or grease from the metal before soldering, make sure you rinse thoroughly after cleaning. Steam-cleaning you piece also works.
  • Fitting:  Make sure your solder joints fit tightly together before soldering is a must. Any gaps between your parts will create a solder joint that is weak and could break, mismatched solder joints could also result in pitting of the solder.
  • Flux: Is used to prepare the metal surface to receive the fluid solder. The applied flux must be in contact with the solder at all times, make sure it touches both metal parts that are being joined. Some self-pickling fluxes also help dissolve oxides. To create the ideal soldering surface, keep the joint oxide free.
  • Flow: Solder flows towards the flame and the hottest part of the surface. Concentrate the flame on the surrounding surface of the joint to be soldered, than on the joint, the surrounding metals must reach the desired temperature before the solder will flow.  
  • Pickle: Mild acid pickle can be used to clean nonferrous metals, removing any oxidization and residues before finishing your piece.
  • Storage: Keep solders clean and free of dirt and grease. Silver solders may be cleaned to remove dirt or residue.
  • Cleaning Sheet Solder: Use a pickle compound and then straight denatured alcohol to clean sheet solder
  • Overheating the solder, excessive heating can cause porosity. Solder will not follow onto a piece until the temperature of the piece reaches its flow points. Use direct heat on solder joint not the solder.
  • Using the wrong solder on dissimilar metals, when soldering tow dissimilar metals together, use the lower temperature metals for soldering. For example, when soldering silver to gold, use silver solder.
  • Using soft solder or repair solder when sizing. Use a hard solder when sizing to prevent porosity and avoid seams.
  • Tumble Finishing: Successful tumble finishing has been done using rough cut with epoxy cones and triangles in a vibratory tumbler, and also by using a steel shot mixture in a rotary tumbler. It is very important to maintain clean shot and solution.
