So facts are this. 1075 steel Heat treat failed first time, file bit in Normalization x3 Re heat treat, went better I think. After temper cycle it passed brass rod test. Fished up everything and dunked in ferric Chloride.
Here’s the weird thing: Brad got black fast. Tang grey below the quench line. I thought the hardened steel was supposed to take longer and then softer Blaken quicker. How am I “backwards”?? Totally lost. Blade looks great, just scared I made a POS..😞😔☹️

That's it, the stronger the acid mix the quicker it turns the hardened metal dark. You're good to go I'd think.
