Description:

Non-Smoking Non-Fuming Odorless Flux
Far and away the most popular - and successful - bullet casting flux, MARVELUX has been on the market since 1971 filling the needs of knowledgeable and successful professional and hobbyist bullet casters. MARVELUX is non-corrosive to iron and steel, and does not produce fumes which can cause corrosion, as does sal-ammoniac (ammonium chloride). In fact, regular use will keep your pot free from rust! Reduces dross formation dramatically while increasing fluidity of bullet alloys, making it easier to obtain well filled-out bullets. MARVELUX is well suited to any lead alloy melt intended for casting bullets or swaging cores. Non-smoking, flameless and non-smelling. Superior to beeswax, tallow, paraffin, and other grease-type fluxes. Even better than rosin and it doesn't smell like you're burning down an old shed.

Brownells USA Best Flux I have found 09/11/2014

I have been casting for almost 50 years and like most old casters I used to use beeswax for a flux for my salvaged range metal. If you have used salvaged bullets you know you get a little bit of everything along with the lead. Wax as a flux smokes and sometimes ignites, but it does work.



However, once I tried a jar of Marvelux I have never used anything else. It is a coarse granular powder that stays on top of the lead. It doesn't take a lot of material to do the job and a one pound jar last a long time. Once stirred in it helps the metals blend and the impurities to bond together and rise to the top where they are easily skimmed off. It doesn't smoke and ignite and does a far better flux job than wax. The powder does tend to cake in the jar, but it is easily broken up with a spoon. I read one negative post about Marvelux causing rust and I honestly don't know what he is talking about, if anything it keeps my pot clean and free from buildup and certainly no rust. If you haven't tried this product then you are still doing things the hard way.

Not recommended

Brownells USA Be careful 24/09/2014

If you absolutely need something with minimal smoke/smell, Marvelux works OK. Be very careful though, as it is seriously hygroscopic (attracts moisture) and leaves a sticky, glassy residue that's hard to get rid of. I had bad rust problems when I used it, and threw away the rest of the can. I think it can work ok if you're very careful how you use it, but many/most serious casters hate it with a passion. If you don't believe me do a search on cast bullet forums. I'm far from the only one who's had problems.
