There are two things that I will not do anymore. The first being the smelting/mixing of alloy or melting dirty lead in my bottom pour pot. The second is using marvelous flux! Both of the above make for a very filthy pot! Especially the Marvelux!! I hunted all over for my Lyman 10 lb. pot and think it is forever lost due to one of my moves. So I ordered another one from Lyman last Saturday & received it today. I really like the cast iron pot & sitting here looking at it brings back fond memories of my early casting days back in the very early 70's. The new pot is made just like the old one . . . Thick & heavy! It is easy to clean with nothing to clog up. I've already made a steel stand for it with accommodations for holding a propane torch . . . Just like I did years ago. Although Marvelux flux does work OK, it makes a mess of the pot. It leaves a dirty black crust in the pot which I have no need for. Back to candle wax as that has always worked the best for me.

I never have tried Marvelux , always used old candles or discarded lubed bullets for fluxing and it works okay as long as I don't go overboard with the lubed bullets !

 

I also only have Lee bottom pour pots a pair of 10 pounders and a 20 pounder .So those are my only choices fr smelting WW's and scrap .

And so far KNOCK ON WOOD I've not had any major problems !

 

Now watch me fire one of them up next week and the thing blows up .>

I agree. I found a “used” container of Marvelux at a local gun store and used it for one season's bullet casting. My bottom-pour pots were a mess at the end of the season. I scraped all of the crap out of the pot and have never touched the stuff again. I like candle wax much better.

Oh Noble Pigslayer; After only desperation did I use my last bit of Marvelux. One product Brownells will not ship to me in the future. I have been thriving on the flux supplied by NEI molds. Received my first batch from old Walt himself. One thing I learned quick from the neat old guy was just doubt him, he would give you all kinds of stuff to prove he was right! Seriously, NEI's flux is great. A little smoky but it smells like burning pine sap. I like it. Beats Air Fresh! Cost? Haven't a clue as they always just sent me some or gave some away with a mold order. A “Little Pinch” goes a long way. Like their molds, great product and I haven't a clue what it really is, nor do I care as it works.

Amen, Uncle Russ. I've used it ever since I got my first NEI mold many, many years ago. Even bought two bags of it. My experience before that was with Marvelux and mirrors what others on here say. Why you can even buy the stuff is beyond me.

Good old pine sawdust does the majority of flux duties. I favor a scrap 2x4 with lots of knots and cut it up with my Skil saw. Another flux is shaving from planing pine off that works well for me.

Marvelus...yuk!

Finally cleaned all the Marvelux crust & crap out of my bottom pour pot. What a mess!! Removing that stuff is like scraping down concrete forms after a pour! Whoever invented that stuff should be . . . well, never mind! Went to the grocery store today & along with my groceries I bought a lb. of canning wax. That'll do just fine for fluxing . . . Always has before!

I've started using the flux sold by Pat Marlin. Works darned good before that I tried all sorts of stuff, toilet bowel seal rings, the Marvelux stuff, and candles. I finally settles on the sawdust from the lumberyard (Free- they would have filled the bed of my pickup if I let them) but then I received a little of the flux from Pat Marlins and was hooked. I've read that the wood or sawdust fluxes will pull iron and copper oxide out of your melt, all I can verify is that it works extremely well for me and has a pleasant (campfire) smell. Leave the Marvelux for someone else to suffer with, nasty stuff.

Marvelux is great for brazing as it forms a glass like cover over what you are brazing and prevents oxidation. I only tried it once in a lead pot. That glass like crust all over the inside of my lead pot was very difficult to remove and it didn't flux very well at that. No more of that ......stuff for me.

I use a kitchen pot on a colmen propane stove to melt dirty lead into ingots then i melt them in a different cast pot on a hotplate. also i only use candle wax for flux. works well. i shoot unlubed pure lead so the little candle wax resadue on the bullets helps.

Thanks to TRK, I bought and have been using, 20 Mule Team Borax.  It keeps the melt from oxidizing, but I'm not sure about actually fluxing the melt; I hit the melt with either my wife's discarded candles, or some canning paraffin she bought me, then about a half tablespoon of Boraxo.  The system works great for me.  I have a container of Marvellux that I'm waiting to give to someone I don't like.  As an aside, I've been to Furnace Creek Inn, and other Death Valley sites often; have seen an original (they claim) 20 mule team wagon.  Huge!  Really worth the trip over from my then-home in Las Vegas.

My wife and I both love Mini Baby Bel cheese which comes wrapped in red wax.  I just squeeze the wax wrappers together to make a ball and then cut off a piece when I need to flux.   Mike

I used to use Marvelux to flux with but also agree that it really leaves the sides of the pot filthy. Then I read about some fellows using pine saw dust and I have been hooked on that since. It's cheap (which is good) plentiful as a friend is a cabinet maker and a little goes a long way.

I just sprinkle it on top of lead that is up to casting temp burn it off with a grille lighter and stir it in, then I use a piece of cedar shingle (been using the same piece for 10 years) to gather all the dross in a little pile and scoop it off with a stainless steel spoon.

My Marvelux is now only used when I smelt wheel weights and other lead outdoors in a larger cast pot.

Yup, agree wholeheartedly with all these comments.....I started off using the Marvelux some time back and quickly gummed up the works with the scale it left behind...spent ages cleaning the pots after each melt.

Suggestions of various wood shaving and dust all work but I found pine especially did not flux as well as some of the other hardwoods...found it tended to flame before the fluxing effect took on but it does work if you work it right.

I now use a mix of bees wax and paraffin (candle wax) left over from lube making - doesn't need much, tea spoon at most and never leaves a crud deposit which is what I like about it..smells great but tends to attract the bees in large numbers here so I mostly brew it after dark - am sure there are numerous brews suitable but for me, wax is the way to go.....just my two bobs worth

Bill The borax does keep the top from oxidizing, and it mixes with the crud that comes to the top.  I find if I use a wood stick (wedge or 3/4x1 10” long scrap board) that the mix cleans up quickly. 

Whatever.  If it works and isn't poisonous use it!

I use the pet bedding pine shavings from Walmart for fluxing. One bag is basically a lifetime supply. For reducing I use the parafin wax.

I've used Marvelux, bullet lube, beeswax, and deer tallow.  I'd rate the products as; Best to worse:  Deer tallow                          Beeswax                          Bullet lube                          Marvelux

Marvelux for me is just awful. If I had tried it first when I started casting I would have quit right there.

I've been using Marvelux for several years now in my Lee 20 pound pot. I preclean all my lead in a cast iron pot so only clean ingots go into the casting pot. The last couple years if I don't have the pot temperature up well over 700 degrees I can't get it to flow thru the bottom pour spout. After reading all these comments I'm beginning to think the Marvelux might be the reason for the lack of flow. As much as I hate to do it I guess I'm going to have empty the pot and clean it out. I have plenty of old candles I can use for Flux and saw dust is no problem either.

Corn meal works well as flux and as a cover for the top of the alloy when casting.

I did not have any cat litter and first used corn meal for sealing the alloy after fluxing. I noticed the bottom of the seal had dirt attached and began experimenting with small amounts of corn meal as flux.

Small amounts spooned onto the molten lead, then stirred will work This mixes well, the alloy slightly boils and the turbulence brings the crud to the top. I add more corn meal, light off all the crud and skim everything off. Then I dust the top with corn meal, light it to stop the fumes and cast.

I think the corn oil is the magic ingredient for cleaning, the organic matter burns and seals the pot from air oxidation while casting.

Absolutely BEST flux I have ever used is Vitaflux, by Rich Graphic Products, Imperial Metal and Chemical Co.,, Chicago, IL 60650.

One stick 3” x 1” diameter treats 1 TON of linotype metal in the old hot type machines. Stick is graduated into ten sections, each thick wafer treats 200 pounds of metal.  For 50 pounds of metal use 1/4 of a wafer, for a 20-lb. pot full I touch the stick against the surface of the melt for 2-3 seconds and remove quickly to melt off about 5-6 drops of the melted flux onto the melt surface.

Directions say to “Stir metal until dross is reduced to fine powder, skim and reduce dross and replace with equal weight of “Imperial Plus Metal."

Kester 951 flux is comparable.

Ed,back in the 70's when I was scrounging every print shop I could find I, I grabbed those flux sticks. They are even conveniently covered in tin. I even have a bunch still in the card board dispenser that hung on the wall like an old time match safe. I ration it carefully.

Well, I guess I get the dumba$$ award! I have been using Marvelux for years and never cottoned to the fact that it was causing all the crud in my Lee bottom pour pots. Okay, out with Marvelux and in with wax. I remember using toilet bowl rings, and they seemed to work okay.

I have only ever used Lee bottom pour pots. I have 2 10 lb, and a new 20 lb that I haven't found yet, after my last and final move. The older 10 lb has melted a PILE of wheel weights. It sees duty as the pot for initial melts into mini muffin tins. Other than occasionally cleaning the spout, neither has ever caused me any grief.:)

I wish I had read the last post a bit better.  I tried the Borax. Had 2/3 22lb pot of Lino. Was going to Flux after all the sprues melted down. Saw the box of Borax in the back porch while doing laundry as I waited for the pot  to come up to temp for fluxing.  What the h**l I'll give it a try. BIG HEAPING TABLESPOON!!!!!

BAD ! BAD ! BAD ! , it "Fuomped up" I pulled the dipper out of the pot & started cleaning the "inflated" borax crystals out of the pot with the ice tea spoon that I use to skim of dross with. Took a good long time. Then I fluxed with my usual used beeswax. Got about 3 specks. Guess the borax does work. Just not so much next time.

I too get by "beeswax" from cheese "wrappers".

Marvelux is D****D nasty stuff. I hate  it with a passion.

Maybe we are using too much borax (marvalux). I know that borax can leave crust on top edge of pot, but does it leave ash trapped between pot and melt. Ash is what causes most voids in cast bullets.

I like a flux that leaves less ash residue trapped between melt and bottom of bottom pour pot. Saw dust is the worse. Be sure to scrape bottom and sides of pot well when fluxing before using bottom pour pot. 

Wax leaves ash behind also...trapped between melt and wall. Less is best.
