I'm confused. I'm new at this, so I'm not familiar with the technology terms. I was referring to the pot, not the lid. The handle is flat on top and has a number, and the IN (I assume that means inch) looks the same. How the foundries put the handles on the lids has always been a mystery to me. Now, thinking about it, I'm not even sure how they attach the handles to the pot. I just assumed they were poured with the body of the pot. This post has definitely opened a big blank spot in my knowledge of cast iron production. My lesson for today is how much I don't know.
