arsenic

[Oklahoma Rebel]

can arsenic only be found in existing alloys, I was thinking adding .25 percent to lyman #2 might help with heat treating..?

[rwadley]

No, but it is considered safer to use lead alloys with arsenic to your mix than adding arsenic to lead. There are other grain refiners that are safer like sulfur and copper.

[Der Gebirgsjager]

Arsenic is something I would stay away from. It is usually naturally occurring with lead and finds its way into many alloys, but that is different and far less dangerous than handling it in a concentrated form.

arsenic just speeds up the process.

[Oklahoma Rebel]

so copper does the same thing then. what do you think 1/4%?

[Oklahoma Rebel]

I thought people fluxed with sulphur.?

[Yodogsandman]

COWWs have all the arsenic you need. You only need a trace amount for HTing.

no arsenic and copper do vastly different things to an alloy.
sulpher is used for a couple of things.
it will pull zinc out, it will clean the alloy, and it will act like a grain refiner.
it is also a precipitator like arsenic is.

what arsenic will do that sulpher doesn't is create a high surface tension on the alloy.
it is used in shot to help pull the spheres round because of that ability.
a high arsenic content in your alloy will also cause rounded edges when cast.

Need to be careful with any dross that has arsenic in it. When in contact with water it can for arsene (sp?) gas. What really gets it going is if you have any calcium contamination, like from maintenance free batteries, there is a warning in one of The Rifleman issues.

[too many things]

you CAN buy it but its VERY expensive as runfive said ww will get all you need
last i got was about $30 for 10grams and that is about the size of 4 popcorn s , before they pop
but little goes a long way

[Oklahoma Rebel]

ok, sounds like I have plenty of ww's, I am going to be making another 120lb batch of lyman #2 using about 100lb of cow's 5 lbs of roto's 70pb-30sb and about 4lb's of tin ( solder)

[Oklahoma Rebel]

so thanks guys, wont be poisoning myself this month, stay tuned for next month!!

[runfiverun]

if only you were kidding.
:kidding:

lol tell me about it

I read through paragraph #8 "At this point...." The author seems to contradict himself here, or is not clear: a typo; poorly punctuated. I don't know. What did I miss? Anybody? I stop reading when I
find one of those.

As I understand it, Arsenic was added to increase surface tension to make nice round shot from drop towers. That process is mostly gone, but I think shot still contains Arsenic and as such, a source if you want some in your pot. You might aught to wash the graphite off first as it is a thermal insulator.

[too many things]

not sure if the problem is 8 or 18
NY could have something to do with it
the amount of arsenic in shot /ww is so small that you could not tell /only by the way it works in shot. has NOTHING to do with cast boolits
one piece or pure the, size of a BB will treat 50LB of lead. That BB size will cost about $10 to 20 maybe more now

I love the can of paris green! we had a barrel of it around the farm when I was a kid and my grampop said he remembered dusting it on potatoes, ending up green with the stuff but no one was poisoned...well they had a few mysterious deaths of farmhands but since they were "no accounts" no one cared. Who knows; alcohol, chew, paris green, hypothermia, too many birthdays? Anyway, now that I'm involved with toxicology I realize how erratic and unpredictable arsenic poisoning is, great to avoid direct contact with any metallic salts and if you taste garlic...bend over and KISS YOUR *** GOODBYE!

[Oklahoma Rebel]

taste garlic? is that like what I hear about smelling burnt toast before a stroke?

[waksupi]

A tablespoon of hard shot will add arsenic. Lead already contains some arsenic, as they are together in the natural source. Removing it isn't a consideration at the smelters.

[Oklahoma Rebel]

oh youre talking about actually tasting it, I thought you meant that was a side effect or a warning sign that you have arsenic poisoning.

[quail4jake]

Sorry if I gave you the impression that it tastes like garlic if you eat it (maybe it does?). Arsenic smells garlicky and if you absorb any significant amount through the skin or any other way it will cause a garlic taste in your mouth, so if you taste it you are poisoned and probably enough to cause damage. Often when there is enough toxicity to cause symptoms it is mistaken for something else and the window of opportunity for chelation and dialysis to really work is over. That's what I meant by kiss your *** goodbye.

[Oklahoma Rebel]

who would taste it anyways,'sides maybe a baby?
