Nice work on the bar Joshua!

Thanks Unfortunately, it is not enough for the intended project. Fortunately, that project is already in the works using different material.....

Yeah, Alan said it already- the oxygen in the scale steals the carbon from the iron leaving behind more iron and producing more CO. There's no carbon in fire scale.

I cut the goobers off today to check consolidation and carbon content. The bar laughed at my band saw and I moved to the angle grinder with a cut-off wheel.

The end grain is still pretty porous. I will do another welding heat to consolidate the bar. Hopefully, the carbon content will not depreciate significantly.
