Fluxing linotype metal

Jun 07, 2010 12 Replies

Hi all -



We have acquired several buckets full of old Linotype metal - it's a mix of lead, tin and antimony (and maybe some other trace stuff).



There's also a bit of dross and miscellaneous floor sweepings mixed in.



We want to melt it down, clean it up and cast into small ingots for future use for making stuff - fishing sinkers, toy soldiers, ammunition, whatever.



We tried melting some down and got a surface film of gunk - not sure what it is, but there should be a way to recombine the oxides and clean up the melt a bit, then discard the real garbage.



What should we use for flux to clean this up? Ammonium chloride? Borax? Something else?



Thanks in advance

I called my stockbroker yesterday and asked him, "What are you buying?" His answer: "Canned goods and ammunition."



Got any beeswax candles? Pinch off a piece about the size of a large pea and mix it in really well. Scim off the brown stuff and floor sweepings, then repeat.

Lighting the smoke cloud with a match will help reduce the stink, or simply do it outside.

There are a number of commercial fluxes, but good old wax works fine. As does bullet lubricant from your cast bullet sizer.

Lots of that sort of thinking going on in odd places these days.

Don't waste linotype on sinkers and such. Sell it and buy cheaper and better alloy for that. Give me a price on what you have as it sits.

Indeed. Linotype is a special alloy that is GREAT for making bullets. Best stuff around.

Nickle/tin or nickle/lead babbet is good for sinkers.

You can't really "recombine" the oxides short of a smelter. Beeswax works for fluxing, awful expensive unless you have hives, just a plain old white stearate candle works from the thrift store. Just a fast dunk. If you just gotta, there are plumber's candles that can be had at the hardware store, same stuff, though. All it does is glob together the oxides and crud for easy skimming. Get a stainless soup spoon from the same source and use that for skimming. I use an old tin can for depositing, definitely NOT something combustible. Linotype is NOT to be used for sinkers, way too expensive, also very hard. Swap it for some cheaper lead, if you can, if all you want is sinkers. Linotype is a departure point, you add lead and some tin, usually in the form of bar solder, to make up other alloys, Lyman #2 is frequently what's aimed for. Lyman's cast bullet books have several receipes.

cheap wax rings used for installing toilets.

Robert, has anyone figured out what the hell they make those out of these days? 'Taint wax, and looks faintly like poo.

Something that I've been using for 30 years of casting....Crayons

Usually you can find a bunch that are being thrown away at the local elementary school.

They work very well, and the price is right

In addition to all the other suggestions, Beef tallow or Dripping works very well.
