Do you need flux to solder jewelry?
Silver and gold jewelry require hard soldering. Copper, brass, and bronze components can also be fused with hard solders. In addition to requiring flux, hard solders generally also require the use of pickling solutions to clean and remove surface oxidation from the finished piece.
What flux is used for gold?
Sodium Nitrate belongs to this class of flux elements. Sodium nitrate oxidizes metals like iron, copper, and zinc by liberating oxygen at a temperature of about 500oC. Litharge is basically a monoxide of lead (often yellow in color) which is used as gold smelting flux.
What flux is used for silver?
Stay-Silv® White Brazing Flux
This is a white paste flux that’s used for 90% of silver brazing applications. White flux is useful for brazing copper, brass, steel, stainless steel, and nickel alloys. It has an active temperature range of 1050 -1600°F (565 – 870°C).
What is silver flux?
Silver Brazing Fluxes
Fluxes for silver brazing are typically composed of potassium salts or fluorides and borates in a water base. Several flux types are available to cover all possible base metals and/or conditions during brazing.
What is borax flux used for?
Borax is used as a flux when forge welding to prevent oxidation of your surface and weld. The best type of borax to use is generally anhydrous borax (Amazon affiliate link), as it speeds up the process due to its early liquefaction, and leaves little room for impurities to get inside the joints in your weld.
What metals can be solder for jewelry?
Solder, a metal alloy of silver and copper or silver and zinc, is used to join two pieces of metal together. Solder is heated until it flows and then allowed to cool. Once cooled, the join is permanent (if done properly). Use silver solder when soldering copper, brass, sterling silver or silver-filled metals.
What is pickle used for in jewelry making?
Pickling is simply dissolving firescale from the top layer of your piece after it has been heated. It’s called pickling because jewelers used to remove firescale with a solution of alum, which is the same compound used to make pickles.
Can I melt gold without flux?
Never melt fine gold particles using a propane torch without applying flux—this will result in massive losses as the force from the torch will blow the gold particles into the air, leaving you with little or nothing to smelt.
What is jewelry soldering?
Duration. 2-4 hours. Soldering is a process where a metal alloy, referred to as solder, is heated to its melting point. The solder can then be used to form a bond between two pieces of material. Soldering jewelry is an option for those in search of DIY fixes for broken parts like clasps, clips and cuffs.
Can you use 20 Mule Team Borax as flux?
I have been using 20 Mule Team Borax mixed with water as my only soldering flux for over 25 years and have never had a problem with it. I do use the finer gra.de commercial Borax as my flux for casting. out. It is just that it has a fairly high melting point at 1367F.
Is soldering paste the same as flux?
Solder paste contains solder particles and flux. It helps ‘tin’ a surface with a coating of solder, resistant to oxidation. Solder Flux is just ‘flux’, a chemical to clean the surface, ready to accept solder. Solder has to be added in order to make the joint or tin the surface.
