I use sawdust for flux.
Works the best for me, but smokes.
I have a fan vent, so not that much of a problem.
The sawdust turns to charcoal.
Has anyone just used charcoal to flux.
My thinking it would cut down on the smoke.

Just put a match to the flux and it will stop smokingQuote:

Charcoal should work as a flux but would need broken up to a powder / fine granulation. WHat did pop into my mind reading your question is With my big ladle pot (120 lbs) if a couple briquettes left floating in it would slow the oxidation on top while casting? They would be to big to get in my ladle. I make a swirl when filling the ladle so would have small stir action every cast. Might make a more consistent mix start to finish
My saw dust turns to ash, not charcoal.
I don't think I'd use Kingsford BBQ charcoal, while it might work ok, it seems like a waste.
Briquettes are not charcoal which is made out of wood. BBQ briquettes are mostly made out of coal.
My bag of lump charcoal always has some dust in the bottom of the bag. Normally just dump it in the yard.
Think I'll save it and try it as flux.
I don't see why real charcoal wouldn't work as flux, most recommendations are for a carbon based product and charcoal is carbon.
In Elmer Keith's first book, "Sixgun Cartridges and Loads" he recommended a layer of charcoal on top of the melt to reduce oxidation, if I remember correctly.

Actually, briquettes are indeed made from wood. Charcoal is partially burned wood.
The Kingsford Company was owned by Henry Ford. Instead of throwing out all the hardwood crates in which his materials came, he started making charcoal from them, and got another revenue stream.
The Kingsford plant is located in Springfield, OR, just off Hwy. 126, which is the main highway between Eugene and Bend. Every time we go east, we pass that plant, and the huge piles of raw material are wood, not coal. They make the briquets out of wood products.

Hope this helps.

I used wood ashes, like from a fireplace or camp fire. I don't remember having a lot of problems getting good boolits.
Kingsford briquettes have something mixed with the charcoal so they can be formed in the little briquettes ...I believe it's Charcoal , Cornstarch , Sawdust , Sodium Nitrate and water ...the mixture is formed into the briquettes and dried .

I'd heard the wooden crates for engines & such were made to a spec. where they could be knocked apart,
and dropped in during assembly as the floor boards. That was done on the Model 'A's too.
Other crate pieces went into the wooden door and body frames for the upholstery to be attached to.
Whatever was left of the crates went to Kingsford.
Yep, ol' Henry even specified the engines be delivered in crates of certain size, bolted together with certain bolts, the bolt holes in certain places.
When the engines got to his factory, they unbolted the sides of the crates, and used those same bolts to drop the un-altered crate pieces into the floors of the Fords on the assembly line. Even the holes where in the correct places.
The folks making his engines also made his floorboards.
Charcoal briquettes sold for cooking food can include:[5][6]
Wood charcoal (fuel)
Lignite coal (fuel)
Anthracite coal (fuel)
Limestone (ash colourant)
Starch (binder)
Borax (release agent)
Sodium nitrate (accelerant)
Sawdust
Wax (some brands: binder, accelerant, ignition facilitator).
Chaff (rice chaff and peanut chaff)
Read the package for ingredients. I get real charcoal (made of wood only) and it works fine.
I make charcoal in an old ammo can. Take the rubber seal out, burn the can in a fire to remove the finish. Stuff it full of wood, close the top, put it in the firepit upside down. Start fire, remove can in a couple hours and let cool while closed and still upside down. Open and enjoy.
I have been using my old walnut tumbling media for decades to flux with. I have even added oil to enhance it when it burns down it is basically just little pieces of charcoal. doesn't smoke and recycling is part of the fun.
I use sawdust that has been used as handcleaner after oil changes; it scrubs your hands while soaking up the oil. Also use sawdust to clean up oil spills, then use as flux.
Wife and I just talk about the trip to Cass Railroad in WV. Kingsford Plant down around that way. Huge pile of wood chips, Where talking huge.
Don't forget the safety factor, charcoal produces carbon monoxide which will kill you if used in an enclosed area.
