Product Information

From the reviews I read it just seems that cold blue solutions are adequate at best, and are most often disappointing. The very same "black oxide" solution which gives a dark black on matte parts gives a jewel blue on mirror polished parts.

Instead, hot blue your whole weapon and use cold-bluing to touch up scratches and small rust patches that may appear over time. Simple parts need to be soaked for 15 to 20 minutes, while complex or decorated parts should be soaked for about 45 minutes. The blue appearance of the oxide film is also used as an indication of temperature when tempering carbon steel after hardening, indicating a state of temper suitable for springs.

The straightforward application process minimizes the learning curve and ensures that anyone can effectively use Ballistol Quick Blueing without extensive experience or specialized tools. weight, ¼" NPT pipe thread, and it requires specific water column gas pressure: 11" for LP and 4"-6" for Natural Gas, with a 25,600 BTU rating. To reduce sludge generation, use de-ionised water instead of tap water to make up your bluing solution.

At the end of this heating process the crucible is removed from the oven and positioned over a bath of water with air forced through a perforated coil in the bottom of the bath. The mixture is heated to 310 to 321 °C (590 to 610 °F) and the parts are suspended in this solution with wire. All Powder, Primers and Ammunition are classed as hazardous materials and therefore must be dispatched using an authorised Hazmat carrier. Bluing may be applied by immersing steel parts in a solution of potassium nitrate, sodium hydroxide, and water heated to the boiling point, 275–310 °F (135–154 °C) depending on the recipe. The metal surfaces are block sanded to remove all imperfections and then polished to a mirror shine just before the bluing process, which avoids oxidation of the steel.Mfr Part: 41 No damp cabinets or long rusting periods required to get top-quality, good-looking blues and browns. I have since read that some of the old rust bluing formulas contained cyanide which have since been discontinued for obvious safety reasons. I have rust blued four 1911's over the past five years, and the finish on all of them has held up very well.

You can neutralize the mix with vinegar but it causes an exothermic reaction - so you don't want to do it on flesh. Hot bluing should never be attempted on aluminium, as it reacts it usually dissolves in the caustic salt bath. undergoes an extremely large volume change upon hydration; as a result, the oxide easily flakes off, causing the typical reddish rusting away of iron.

When you boil off your rusted barrels, do you wait for the water to boil and then immerse the barrels or immerse the barrels in the water and then bring to the boil?

Using cold water to remove all traces of detergent will take longer, while hot water will do the job faster and more thoroughly. In colloquial use, thin coatings of black oxide are often termed 'gun bluing', while heavier coatings are termed 'black oxide'. You may need to deal with substances from your bluing baths as hazardous/special waste because they have corrosive and irritant properties or are contaminated with heavy metals.
