I have some mystery lead.

[ScottJ]

Have some mystery ingots. The small ones between the muffin ingots here. I think the shiny ones on the right are foundry type or something like that. Not sure about the others guess I'll have to invest in a hardness tester or just mix them 50/50 with something hard.

Then from the back I have these 4 block strips that appear to come from a commercial supplier. There're quite soft as I'm able to dent them significantly beating them on the concrete floor. I'm thinking they're pure lead.

Here's a couple other pics from today's big melt and organize. I got a small supply of lead pipe. The misc are a mix of fishing sinkers and range scrap:

Here's the whole stash:

I wish I had that problem.

Nice batch of ingots

Just watch how much you stack in there
Lead is not light

I put to much on a shelf in the basement
It now is laying on the floor where the shelf was

The square ones are most likely plumbers lead. Pretty close to being almost pure. I've seen them as round hockey pucks attached to one another with 5 altogether. Also seen them as large ingot shapes as well. Frank

Yep, plumbing lead is my guess for the square ones with the raised lettering. It seems to me that my pure lead ingots turn dark grey much quicker than alloy ingots.

Just a guess, but 'LP' may stand for lead pipe.

Having a hardness tester is a real blessing for solving mysteries like this. The Lee tester works great for me but currently none are in stock anywhere. I use it to BHN test wheelweight and range lead ingots, then calculate the amount of high-antimony lead (Superhard or type metal) to add to get a desired hardness. I set my casting alloy at 12.5BHN and 2% tin.

The ones written on I know the alloy because I melted from raw material myself. I just threw that pic in because they were shiny :)

What I'm thinking of doing now is snagging some linotype off eBay and mixing it 3:1 with the unknown. Chances are high all of it is plumber's lead since it's all donated from the same source.

Those Hewitt ingots are most likely soft. Drop them on concrete, if they thump they are pure. Harder ingots will clank instead of thump- try it with some alloy you know is harder to see what I mean.

Just ordered a Lee tester from Midway. Out-of-stock, but ordered it anyway. The final screen said it was expected in stock on or about 5-8 June. Nice stack of lead. Mine is growing, but, still not there. Cheers!

Definetly check the tonal quality of the "Hewitt" chunk. They produced journal bearing material and Babbitt. If you tap pure Lead with a ball pein hammer, it makes a muffled, dead sound. Solder alloys have a little more ring when struck. Babbitt has a definite metal ring. If so, you have an ingot with 10%+ Antimony, or higher, and the same percentage of Tin. Hard to say without having it analyzed.

I just checked Midway to see if it was in stock, yet, and NO! the site said expected to be in stock on June 25ish. BIG disappointment!

I have had that Lee tester on order from Midway for 4+ months and still not here. I have read Lee is behind 16 weeks on most of their stuff. Was able to snag a spare 4-20 pot the other day from Graf...5 hours later they were out of stock! Nobody has anything by Lee.

Gave up and ordered a CabineTree and it shipped the next day. Yea, it's double or more the price, but from what I have seen and read it is the new standard for hardness testing in the low ranges we deal in. Will be here Friday! I will use it to double check the Lee.....if it ever arrives. I have two casting shops so....two hardness testers!

Thanks. Glad it's not just me. I hate being lonely.........
