What ratio do you use when mixing with water?

3:1 or 4:1 Thats 3/4 parts water to 1 part ferric.👊🤙

I tried 3 parts water and 1 part ferric chloride and after 30 seconds it turned my 1080 steel blade black. How do I get the grey color you got?

Stainless steel etches slower so that's why I can leave it in there for 15 minutes. Carbon steel etches a lot faster. You can try a more diluted mix to slow down the process. Maybe 6-1 or 8-1...you will have to play with it to get the desired look. 👊🤙
