Purchased this Large 400 Lb. Block of Lead

I am questioning the weight of your block of lead.
A cubic foot of lead weighs 708 pounds. That would 12"X12"x12".
If your block is 18"X18" x18" it would weigh well over 1000 pounds.
BTW, Great haul.
I would go with melting it with a weed burner or some other heat source.
OK. I'll go measure it. It was 400 Lbs on the scale at the metal recycler. I was at the office when I posted yesterday. Not with the block in front of me.

Assuming 0.41 pounds per cubic inch and 2366 cubis inches, using the above measurements, That should be close to 970 pounds.
If it is pure lead, and those dimensions are correct with square corners.

Check for alternative heat sources like wood fire. That much mass is going to take a huge amount of heat to begin a melt with the heat transfer through the remaining block. A daunting task with a big reward at the end.

That was my thought. That's a lot of thermal mass.
I've never tried anything that big, but if I were presented with something like that, I'd probably start with an air chisel or a saw. If you used a wood fire and rigged up some sort of catchment for it, I'd think the outflow would be unmanageable once it started to melt. If one went that route, a leaf blower or wet dry vacuum will help increase the temperature a bunch.

There is a steel sub structure in it to anchor the "I" hook and the lead is filled in around it. So volumetrically it is not all lead and the steel structure is mostly square tubing. I'll keep track for what melts out of it. I figure I'll get 370 lbs. If its more thats great too.

yeah,, i had a scrapper weigh out a lino pig at 20 lbs.
i know they weigh 25.

he wanted to sell me the whole pallet and i wanted WW's, he couldn't understand the concept of not shooting pure lino bullets.
i finally relented for '400' lbs at 65 cents a lb. instead of the entire pallet of pigs at 50 cents.
which meant i got 100 lbs. for free.

I had a chance to buy a semi load of pure lead ingots from a producing mine. I would’ve been able to get 16,000 to 20,000 pounds at $.20 a pound easy. Unfortunately, at the time, I did not have enough cash. I should’ve taken out a second mortgage!

Find an old concrete foundation in the country. Get a half dozen pallets, pile them on and set afire. Get it as it runs out. Come back next morning with a leaf blower and blow ashes off. Should be thin enough th break up. Cut pieces to size with a log splitter. Mine cuts about 2” thick stuff.:beagle

Well the block I had was in a steel box built to fit in between the frame rails of a tractor/ truck that was used to haul Mobil homes. I don’t remember the dimensions but it was about 12”” w x 16” d x probably 20” long. The steel box was open top. After melting it out I had about 1800 pounds. I’m not sure about the dimensions, it was along time ago. Still have the empty box.
There was a second larger box filled with lead as well. I sold that chunk and used my old Cat loader to load it out. Wrapped it with a chain and hooked it to a tooth and the bucket and it was heavy as the Cat was tiptoeing to the buyer’s trailer.
But I brought the smaller one inside my shop and suspended it with a 3000 pound chain fall. Drilled a hole in the lower end and put my weed burner on it with a couple of 13x9 pans and 5x9 bread pans. Shove a pan under, slid out when full. Took a fair amount of time to cool to drop ingot out of the pans.
