why won't steel blue?
« on: March 18, 2017, 06:27:04 PM »
i have a knife i made from an old sawmill blade and blued it
it came nice. so i tried to do someother steels all high carbon and
some )01 tool steel. the results varried from thee blueing turning
a sulfur   kind of yellow to the bluing liquid just puddleing up.

the product i used is called super blue. has anyone ever had this
happen to them? the company is called birchwoodcasey,
which nolonger owns superblue. so i couldnot get an answer
from them.

  The bluing solution could have lost it's strength or changed chemically through age or environment,  or the steel you're trying to blue may not be the high carbon steel you thought it was such as 1095 or 0-1 tool steel,  it could be an alloy steel that resists the chemical agents in the bluing solution.
  I've used Birchwood Casey products with great success over the years, I just blued an axe head with Birchwood Casey Cold Blue paste that was left over stock from when I closed my gun shop in 1975 and it was fine,  I'd say it's probably the steel that's the culprit rather than the bluing agent,  try cleaning the steel with denatured alcohol or other cleaner that will cut wax and oil and not leave a residue behind, you can also use a magnet on the steel piece to make sure it's not stainless or some other resistant alloy.
In youth we learn,   with age we understand.

Try hot soapy water and steel wool to clean then wipe down with acetone. sometimes warming the steel helps.

Warming the steel works for gun barrels.......as super good cleaning.
