Description: Flux powder Use for all precious metals, silver, gold and platinum group as well as all cupreous metals. Jeweller's and Silversmith's soldering flux: Prevents oxidisation of the solder and soldering area. Flux powder which is simple to use by mixing with water to a creamy consistency. Apply to the joint or area to be soldered / welded with a fine brush. Also coat the solder pallion or wire. Apply gentle heat to dry the paste which ensures the solder sticks and does not jump off and then solder as normal. Coating for crucibles prior to metal melting: New crucibles need to be glazed with flux before melting your metal which ensures the molten metal flows freely. Sprinkle the powder in the crucible and apply heat with your torch or kiln. Continue to add small quantities until the whole interior is glazed. During the melting process a little borax sprinkled on the molten metal will help to maintain flow and prevent oxidisation. Further Metallurgical Information:Flux powder has the ability to dissolve metal oxides and is exploited in the recovery of metals such as brass, copper, lead and zinc from scrap or smelting slag. In Iron metallurgy, flux powder is used as a flux to prevent oxidation at the surface of the molten iron. In other metal working processes like welding, brazing, and soldering,also used to cover the metal surfaces. This prevents any oxidation occuring by excuding air and moisture contact. It also can be used as a cleaning agent.A mixture of flux and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide, scale, allowing it to run off. It is also a good flux for "pre-tinning" tungsten with zinc – making the tungsten soft-solderable. Flux is often used as a flux for forge welding. Please Note: This product has been reclassified by the ECHA as Reprotoxic Category 2 and we are supplying it only for the purposes stated above. All safety information should be read and understood before use. Flux has been used as a cleaning agent for centuries:Also has many chemical properties that contribute to its cleaning power.Flux and other borates clean and bleach by converting some water molecules to hydrogen peroxide (H2O2). This reaction is more favorable in hotter water. The pH of flux is about 9.5, producing a basic solution in water, thereby increasing the effectiveness of bleach and other cleaners. In other chemical reactions, borax acts as a buffer, maintaining a stable pH needed to maintain cleansing chemical reactions. The boron, salt, and/or oxygen of boron inhibit the metabolic processes of many organisms. This characteristic allows flux to disinfect and kill unwanted pests. Borates bonds with other particles to keep ingredients dispersed evenly in a mixture, which maximizes the surface area of active particles to enhance cleaning power.Flux has also been used extensively as an essential ingredient to make scientific toys like bouncy balls and crazy putty and slime. It should be noted though that the updated REACH advice especially for younger women and children should be understood.The 500g comes in a jar 1000g x 2 jars, smaller size 200g comes in resealable packets.
