I was finally able to put a chemical wash on the steel to blacken the surface to match the black-oxide hardware I bought for the table. The two close-up photos are of two test pieces I did to figure out how the chemical worked. It took a lot of trial and error to get the pieces how I wanted them. I tried multiple coats, brushing it with steel wool between coats or after the final coat, and different application methods. I honestly still don’t understand what it takes to make this stuff work well because every time I did a test piece, I’d get different results.
The last picture is my final piece finished. There was a moment of panic when the steel turned yellow after my first coat and I had no clue what had happened. I wanted to take a picture, but was so freaked out because it hadn’t happened on any test pieces. Fortunately, most of the yellow dust that formed, I think through oxidation, easily brushed off. After a second coat of the wash and the final coat of the spray on protector, it looked really nice!
