Was wandering what you guys do when you have a peice of steel that randomly gets a spot where the mill scale comes off like the bottom hinge on the left side in the picture it's in a section that wasn't really worked I like natural finishes best wax and linseed I know paint would obviously work but I hate hate hate blasting nice metal work with chinsy looking paint I tried to sort of blue it with the o a torch but actually made it worse just curious if there's some secret thanks Mike

IDK, I will heat it orange hot with a torch and brush the heck out of it as it cools.

Seems to only happen on hot roll I tried the torch but it started flaking like powder coat coming off i usually just toss whatever in the forge and like you said brush it good but didn't want to with the already assembled and adjusted hinge assy I'm thinking about trying a mild acid dabbed on the shinny spots

You just need to learn that a wire brush is your best friend. I wirebrush at the end of every heat. Learn to see what temp it is scaling. This is where you start, even before striking with a hammer, then keep it up espscislly down thru a dull red. This is how you develop a beautiful finish on your forged iron.

Like every thing else, wire brushing is a learned skill.

Agreed I try to brush often or your just asking to pound a cold shut into it .I should have heated the whole thing up till it scaled and brushed it the peice was 24 inches long and I only worked the ends so where forged met unforged the original mill scale started flaking I lightly sanded it and aged it with strong vinigar on the shiny spot which worked well after some hot wax it looked fine in the future I will work the whole peice lesson learned
