I'm glad you said that they never "really go bad"....because they can.

In my personal experience, I've had molds get so hot due to mass production that the lead wasn't solidifying fast enough that I've opted to dip the mold into cold water to keep things moving along. (Keep in mind that I was using a large pot...you wouldn't have this problem with the pot in your picture)..This ended up warping the mold causing sinkers to not form correctly.
Meaning that the mold warped in such a way that the hole that you'd thread the line through no longer formed. I would have to drill and grind the hole clean after pouring. This would double the time it takes to make the product. So be careful buying used molds.

Buy a brand new Do-It mold and get on with it.
Be careful as water and lead do NOT play well together. Use a metal spoon to sift off the debris from the top. I've found that by leaving some melted lead in the pot, it helps to start the melting of newly introduced lead. Wear safety goggles.


Be safe and pour in a well ventilated work space.
