Rust or clay?

At first I thought this was rust on this old bell at the Lee County Courthouse, but the more I look at it, the more I think it's clay. It gets everywhere, and since it's orange, it's easy to see.

In your shot, it does look like rust, but you are right in that it could be clay. Interesting shot, Lisa.

Great point of view

I think you're right, except maybe on the nut and screw head. I love the textures you've captured here.

@susanalena @digitalrn @randystreat Thanks! I'm going to have to go back with a wet paper towel to see if it's rust or clay! LOL!
