Current Precious Metals Markets Date: 4/26/2024 Silver: $27.65 Gold: $2,344.60

Please read this first: All precious metals are sold by weight. Below, you are able to select a desired weight or length of metal to order. If you order by weight, we will convert that weight into a length to cut, based on the average length per troy ounce for the metal form factor you have ordered. We will cut this estimated length and weigh the cut piece. You will be charged for the actual weight of the metal we send you, which may vary slightly from the weight you requested. If you order by length, we will convert that length into an estimated weight in order to provide you with a price estimate during the checkout process. Again, you will be charged for the actual weight of the metal we send you. Market prices of precious metals change daily, Monday through Friday (major holidays excepted) at approximately 10:30 AM Mountain Time. Adding a metal to your shopping bag does not lock the market price in. The market price will be locked in when the checkout process is complete. Different form factors of the same metal can be combined to achieve quantity discounts.

Silver Brazing Alloys (Hard Silver Solders)

Hard silver solders require high temperature (1200*+F.) torch brazing.
Most fine jewelry is hard soldered (brazed) with a gas torch.
The # of the solder indicates the percentage of silver in each.
Silver solders with higher #'s are stronger, have less color and require more heat.

It is wrong, in general, to think using paste solder will be easier to use than chips or wire brazing alloys.    Paste solder is a mixture of thick flux and tiny silver alloy particles and its primary use is for applying solder to hard to reach areas that could be difficult by other methods. This is the reason it comes in syringes with small hypo tips as typical applications include securing hinge pins, sweat soldering small pieces onto a larger surface and in mass kiln soldering applications. Its biggest drawbacks are that the flux paste swells considerably before shrinking down leaving a relatively small amount of solder (to flow where you want it to).    Paste solder should be heated slowly and indirectly to allow its flux to settle then, hopefully, there will be enough silver particle in place to do the job. For most solder brazing applications, laying down a path of solder chips, placement of melted balls of solder with a pick, and direct application of wire solder are much more effective and economical than using paste solder.

Soft Solders

Most soft solder melt temperatures are around 450*F.
Soft solders can be melted with an electric soldering iron.
Soft soldered joints are much weaker than hard soldered (above) joints and seams.
Fine jewelry is rarely soft soldered but sometimes it is used to join two pieces with large mating surfaces. Example: Enameled medallions on fine jewelry and serviceware are usually soft soldered into place.
Soft soldered jump rings are better than open rings but much less strong as a hard soldered jump ring.
It is usually OK to use soft solder on things like light earrings that are not subject to wear or abuse.
Soft soldering jump rings will help their strength somewhat but hard soldering is the industry standard.

Silver Soldering (brazing)  Tips:
A good fit.
Keep it clean.
Lots of clean flux.
Clean the solder too!
Fire it up and do the job quickly.
Heat the big pieces first.
Dim the lights if necessary to "see" the metal's temperature.
The solder follows the heat - use this to help control where it flows.
Finish by bringing the whole area up to temp. to completely flow the solder.
(even some of the pros don't follow this last step and get bad joints!)
