The B/Ox 311 process is used to create a variety of brown, black-brown, and US 10B finishes. It produces consistent color day in and day out, and it's easier to relieve than other processes.

Health Hazard
Irritant
Specifically, this process produces a black to black-brown US 10B finish on copper and brass with a lighter finish on statuary bronzes. Underlying red tones can be created when highlighting the brown tones.

What is black oxide?
Black oxide is a blend of caustic, oxidizers, and additives that is used on ferrous metals. There are three types of metal blackening: hot, mid, and room temperature blackening. EPi was the first company to offer all three processes.
Hot black oxide (285 F°) is a conventional hot process which produces a true black oxide iron magnetite (Fe3O4) finish. It is a premium-grade salt mixture which will blacken a wider range of steel alloys than any other process on the market.
Mid-temperature black oxide (225–245 F°) is the latest development in blackening processes, producing a true black oxide iron magnetite (Fe3O4) finish. It produces no caustic boiling fumes and provides a safer working environment.
Room-temperature blackening (65–85° F) is the preferred metal-blackening process for safe and convenient in-house blackening. It is an excellent non-bleed black finish for powdered metal and cast iron. It produces super deep blackness and corrosion resistance equal to hot oxide blackeners.
It is important to note this is not a true black oxide process; however, it may be referred to as room-temperature black oxide. Room-temperature blackening processes are autocatalytic reactions of a black selenium-copper compound that deposits on ferrous parts through an immersion process.
What makes EPI’s black oxide and metal-blackening processes better?
Insta-Blak processes do not produce smutty rub-offs like other room-temperature products. Our Ultra-Blak products are premium-grade black oxide, and Kool-Blak does not produce a smutty rub off like other mid-temperature processes. They are easy-to-use with wide windows of operation.
What are the advantages of black oxide and metal blackening?
Ultra-Blak:
Produces true black oxide finish Fe3O4 magnetite finish
Abrasion resistance
Corrosion protection
Meets military spec MIL-DTL-13924D and AMS 2485H
Blackens faster than other hot black oxides
Less sludge generation than other hot black oxides, which means lower gas bills
Insta-Blak:
Capital costs less than $10,000–15,000 for turnkey operations
Energy savings
No CO2 emissions or green house gases
1–5 minute process time for blackening
Powder metal does not bleed-out white salts like hot black oxide
Cast iron and steel castings do not turn red
No ventilation costs
Provides corrosion resistance
Dimensional stability thickness 5–10 millionths of an inch
