Blackfasts' room temperature blacking process is a simple dip operation specifically designed for use in factories.
The process does not materially effect dimensions and a uniform colouring is obtained over machined surfaces, threads and blind holes.
Blacking is achieved by chemical conversion of the metal surface and the process entails degreasing, immersion in a surface conditioner, and blacking solution.
Corrosion protection is afforded by a final immersion in a dewatering oil.
A typical blacking line would be configured as illustrated in the diagram to the right.

basic training : degreasing, conditioner & blacking
- Make sure the metal is really clean (a patchy black means it is not clean enough)
- Keep solution up to strength
- Keep solution > 15 ° C
- Don't overblack (if this has happened, wipe off smut before immersing into oil)
basic training: oiling
- Install a grill in the bottom of the tank
- Drain off displaced water
- Keep a separate basket for the oil tank or degrease the basket after use
- Allow enough time in the oil for water to be shed from the black surface
- Agitate small items
- Rotate those with complicated shapes
- Top up regularly
- Replace lids when not in use
- Allow components to dry before handling
- Don't allow oil to be wiped off component.
