I melted a bunch of WW a few months ago. Used a pair of dikes to check any I wasn't sure about.
Zinc has a slightly higher melt temp so I was looking for any "stragglers" in the pot. They all seemed to melt at the same time.
Pretty sure they were all lead!
On another note. I used a muffin tin to pour them into ingots.
Do not set your muffin tin mold on a milk crate! 😂
or on the wife's grandmothers antique wood cutting board! don't ask.
