Checkout the flaking on this one.

I went all day but didnt find any great things. Pottery and a piece of a stone bowl. My friend found this Heart Stopper but it is broken but checkout the flaking on it. I know it would of been a great one and he was nice enough to give it to me. By the inclusions in the stone I do believe it is Hematite and also the weight of it. Maybe next time a whole one will surface. HH, rock

This is what iron ones look like after over 200 yrs. In the ocean.
I have that in electrolysis now.

I agree with the iron. I think it's slag. Pretty much what Gator already stated. I can see the yellow tint around the edges, where light is penetrating the thin spots. Glass that has been run over and weathered just looks worked. I still pick some glass out of fields and send Gator pics. Just for reinforcement. Gator is the only person that I know, cyber personally, that has found worked glass. Cyber personally..... Wow! That's a pretty wild trip, huh?

The yellow tint is mud. I was standing rite there when he reached down and pulled it from the mud.
