This is some lead that I smelted a week or so ago, this lead is mostly fishing weights and plumbers lead that was found metal detecting as you can see in photo 1 there is a glob that pools up when I pour Indots ,photo 2 shows where I took my pocket knife and shaved the poole off the bottom , when I do so this come off as granuals, It only does this on the pools. the rest of the ingot is normal or seams so. Thankfully I havent mixed this with any of my other alloy ....was hopeing that one of yous guys knows what this is , I have never run on to this before. any help would be appreciated.
