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.
