Yes I saw the grains. But then I saw all the horizontal lines separating them and I noticed the grain was different in some of the sections. Initially I thought it was wrought iron because this was my first time with it but since I have found genuine wrought iron I have come to doubt what this Wagon Wheel is made of. Looks really Gray in the middle then above that very coarse grains and weird lines separating it. Whatever it is it Forge welds very nicely. And the Sparks are not forked and are more red than Orange. One thing I can tell you about this material is that it is incredibly strong I almost blew through a cut off wheel just cutting a piece out then whenever I cut part way through to attempt to break it I have to hang on it it is incredibly hard to break it or bend it . Looks like I stumbled onto some sort of primitive hybrid LOL. But the lines that make the layers of whatever this stuff is should become visible when ever I etch. But no matter what I do I can't bring it out. I must have etched the knife 20 times and sanded it off and started over. It was quite a learning experience as this is my first Forge Weld and attempt to etch.
