Blackening the steel:
A mixture of caustic soda (700g), potasium saltpeter (250g) and water (1,2 l)
The temperature of the solution should be kept between 120 - 140 C.
I keep the knife inside for about 30 minutes to get consistent black colour, you can manipulate the time to achieve different results, shorter period should give you dark brown or purple - ish colour.
Be careful - this mixture is highly corrosive!
Heat treatment:
-Austenizing temperature: 830 C
-Tempering: 180 C
