Lead Idenifacation ??

[SaltyBuckster]

I got this 25 pound chunk of lead from an X-Ray Laboratory.Scratches with a fingernail.That's all I know about it.I need to keep some really soft lead aside for the 1/64 and 1/80 oz. jigheads with my new mold.Any way to know for sure?

Most labs use at least 90% pure lead.

If the pic was in color I could give you more help, but it seems to be soft.

Bruce, ship it to me and i will let you know.

It's probably in the upper 90%. Labs uses the lead to block radiation so it has to be pretty clean lead.

Have to agree - when everything is silver, everything looks like lead.

I had several similar chunks that I sent Hawn. I think he told me that they were mid 90s....

A better pic would help - looking for a dull gray

Here's a better pic,I think,lol.I have three of these now.

The test I use for detirmining the type of lead (hard / soft) is the 'thunk' test.

Drop the lead on a concrete floor. If the sound the block makes clinks/rings/is high pitched/tinny - it's hard lead. If it goes "thunk" - it's soft.

Thumb nail test isn't always accurate - I have lead ingots made from known wheel weight lead (I melted/poured the lead), and I can scratch them w/ my thumb nail. These ingots don't thunk.

I'll try thunking it,lol.I know that I can stab a screwdriver into it.

Your lead looks pure to me.

I haven't used one in years so I've forgot the name of the tool but it has a pin in it spring loaded and measurement scale tells the hardness when the pin hits the metal . Probably find one at the auto parts store. Just looking and knowing where it came from I'd say its 96 % pure.

Well did it do any thunking for you Mr Bruce or are you waiting on Bill to come home and conduct the test for you.

Definate pure - I've seen the same type removed from a renovated x-ray lab before. It's really good stuff - actually in the blocks it's easier to handle the last time I got some was when I was stationed at Plattsburgh AFB, NY and they were cutting up the hugh sheets with a jack hammer!!!!!!!! With Lake Champlain right next to the base there were lots of fisherman!!! just grabbing as much as they could!!!!!!!!!!!!!!!!

Doc I'm gonna find some way to deport you to the Artic Ice Cap and chain you to a pole!!!! LOL. In 1970 I was only 8 yrs. old buddy!!!!! and my Uncle used to pick me up in his CAR!!! and take me fishing - read my reply elsewhere about the blankety blankety CAR!!!!

No vehicle no way to get there!!!! Nephews are gone this weekend to a concert and I'm heading to a different tire place in the morning, tires first then inspection (don't find anything else wrong!!!!!!!!!!!!!!!!!!!!!). cross your fingers.
