Auflux Soldering Solution
The original green ready made flux has been used in the jewellery trade for generations.
Made in Europe by Lippert Unipol (Cannings)

Normal fluxes cause bubbles so navigating solder during fluxing is often difficult.
Auflux Soldering Solution simplifies this respect of jobbing and will breed confidence when soldering more complex jobs.

It will reduce fire stain/oxidation excesses when soldering because of its unique chemical formula. Auflux has a unique chemical formula which has often been attempted to duplicate to no known effective results. Beware of imitation or inferior solutions they generally give disappointing results.

• Auflux will solder gold, silver, copper, brass, mild steel, stainless steel, but not aluminium.
• Auflux has a working range of approximately 550-800°C.
• Can be used majority temperature grades of solders from extra easy to hard (see our listing for the complete range).

Bakers Fluid No.3 is a specially formulated liquid flux ideal for soldering and tinning of copper and tinned materials.
• Easy to apply fast acting economical in use, ensuring sound strong joints
• Zinc Chloride based flux very effective at soldering copper, brass, and pre tinned materials
• We supply fist class solder to use with Bakers Soldering Fluid No-3 code S33171
• Solder copper brass pewter bronze zinc lead, tin and gilding metal

• Borax flux for jewellery soldering
• Dissolves rapidly to form a paste

Borax Cones are used with Borax Dishes and are a traditional way of making your own flux for precious/non precious soldering.
Pour a little water into your Borax Dish the residual water should be enough to form a paste.
Grind down the cone on bottom of the dish using a round motion this will result a soldering flux paste to be formed.
If your left with some flux don’t worry just add water and repeat the process to make more flux.

A flux commonly used when soldering jewellery. Our special form of borax is produced for use by jewellers, silversmiths, gold investment ingot makers, metal workers, etc.

• Our borax is easy to dissolve and melt than ordinary borax.
• Add the flux with tap water to form a toothpaste consistency and apply on soldering joins ware necessary using fine brushes.
• The flux to use when melting precious metals in an electric furnace or with a Sievert torch system.

Easy-flo™ Flux Paste a brazing flux suitable for use with precious metal brazing. It has a working range of 575-825ºC .Easy-flo™ Flux Paste exhibits better life at temperature and greater overheat resistance than many other flux pastes.

Easy-flo™ Flux paste has a low melt viscosity and as such performs well when pasted onto vertical surfaces, and can be useful when brazing stainless steel. The molten viscosity of Easy-flo™ Flux Paste is such that it holds on vertical surfaces. It is therefore particularly useful when brazing joints in positions where other fluxes may have a tendency to run away from the joint.

Product uses: This product is suitable for use on all the common materials, gold, silver, copper, brass, mild steel and stainless steel), but not aluminium.

Conditions for use: Flux paste should be brushed onto the joint surfaces before assembly. Further flux should then be applied externally either side of the joint mouth.

It is good practice to mechanically clean and degrease the joint surface before applying flux. Heat slowly and evenly to the brazing temperature, without local overheating. Use the flux as a temperature guide - it will become opaque and may have some dark patches as brazing temperature is approached. If blackening of the flux occurs this is often a sign of insufficient flux, overheating or flux exhaustion.

Easy-flo™ Flux Powder is Johnson Matthey’s leading brand brazing flux. It is sold widely throughout the world and is recognised as one of the best flux powders available. It is very fluid at the bottom end of its working range resulting in early and extensive flux spread. This ensures that the joint surfaces are well protected from oxidation at the earliest possible point of the brazing operation. This high level of fluidity also helps to reduce flux voids/entrapment in the joint, the low viscosity of the flux aiding its displacement by the brazing filler metal from the joint gap.

Easy-Flo Flux Powder has a working range of 550-800°C. It is most suitable for use with gold, silver, copper, copper alloys, brass, mild steel and stainless steel, but not aluminium soldering.
Brazing is a metal-joining process whereby a filler metal is heated above and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting (liquid US) temperature while protected by a suitable atmosphere, a flux. Then flows over the base metal (known as wetting) and is then cooled to join the work pieces together. It is similar to soldering, except the temperature used to melt the filler metal is above 450 °C.

Easy-Flo™ Flux Powder has excellent ‘hot rodding’ characteristics and adheres well to a warmed brazing rod allowing flux to be transferred to the joint area via the rod. This characteristic has made
Easy-Flo Flux Powder very popular in hand brazing operations where the time to produce a brazed component is crucial.

Clean and degrease the joint surfaces before applying flux.

Flux powder should be mixed with water and a few drops of liquid detergent to form a thick paste. Paste should then be brushed onto the joint surfaces before assembly. Further flux should then be applied externally on either side of the joint mouth.

Hot Rodding is where a warm brazing rod is dipped into flux powder and the flux adhering to the rod is transferred to the joint area. This is an effective fluxing method but difficult to achieve good penetration of capillary joints. It can be used to supplement a pre-fluxed area during heating.

It is good practice to mechanically clean and degrease the joint surface before applying flux. Heat slowly and evenly to the brazing temperature, without local overheating. Use the flux as a temperature guide - it will become clear or opaque as the brazing temperature is approached. If blackening of the flux occurs this is often a sign of insufficient flux, overheating or flux exhaustion.

The flux residues left after completion of the brazing operation are corrosive and should be removed. The residues for Easy-Flo Flux Powder can easily be removed by soaking in hot water > 40°C for between 15 and 30 minutes. Any remaining residues can then be brushed off in running water.

The most common fuel to use in a micro flame/welder soldering unit.

• MEK flame temperature reaches 1300°C
• Use in a micro weld unit to achieve the perfect temperature and size of flame when soldering gold and silver

Please note: For soldering platinum use Methylated Sprits.

Popular ways to be used:

• Atomizer fuel for micro-flame welders (codes MFUK30/60) achieves a higher temperature for soldering platinum, maintaining a torch flame temperature of 3000°C

• After removing a piece that has been held in Shellac (code S31924 ) clean or wipe off unwanted fragments with this solution

• Using the combined traditional mix of Boric Acid with Methylated Spirits to create a skin to prohibit fire stain while soldering (please see Boric Acid code C4361 for instructions)

• An excellent fuel with great burning properties to use in an Alcohol Lamp (A0002)

Use Boric Acid with Methylated Sprits (code C4357) to form a protective skin over pieces about to be soldered, from fire stain.

A traditional favourite with Jobbing/Repairer Jewellers and Silversmiths.
• Please note: This method will only work with 9-18ct jewellery and silver.

How prepare and use…
• Clean the piece as you would before soldering and assemble.
• Mix with 1 litre of methylated sprits (code C4357/C4358) and 150g of Boric acid in a glass or polyurethane container, with a lid.
• Depending on the size of the piece cover it entirely by dipping or brushing on a fine coating.
• Heat all over with a torch to form a white coloured skin, this creates the protective barrier against fire stain.
• Solder joins normally and clean the work as normal with acid (pickle code P5232) fire stain will be noticeably reduced.

Soft Charcoal Blocks

The traditional jeweller’s soldering block.

• Use Auflux and charcoal blocks together to protect the surface of the bench and to create an efficient soldering area.
• Made from select, close-grain, knot-free, natural willow especially prepared and treated for optimum performance.
• Charcoal under the flame creates a reducing atmosphere for a cleaner soldering environment.

The parts protected by the paste never become covered with oxide and
the heat will never reach the jewel.
After soldering, the paste can be removed with water.
Non toxic. Without CFC. Odourless.
