[TheForge] Temper colors

[martin marks]

I am so glad I have you guys to ask these questions. I put some extra virgin olive oil on it yesterday before I gave it to my friend. He was very happy with the work. Thanks again for the advice. I will get some good oil for my shop so I can apply it as soon as I'm finished buffing.

 Ayup, that's what's happening.
 Polished steel is nothing but millions of
 super fine scratches and will patina in a very short time,
 sometimes
 seconds. Spray Windex contains ammonia and alcohol, a strong
 base and a
 hydrophilic plus whatever surfacants they use. Ammonia is a
 popular
 patination chemical most often used with copper alloys but
 is also good for
 controlled iron/steel patinas. It's not as potent on steel
 as peroxide and
 or salt but will still cause degrees of oxidation.
 
 Without some form of anti-oxidation finish you WILL get
 color changes, heat
 will speed them up.

 Martin, unless it's bone dry where you are, polished steel
 should not be
 left bare.
 Even fingerprints will etch it when  bare.

 I do not finish the blades with anything other than windex
 atm. I let the
 people i give these to know that they should treat them with
 food grade oil
 after they are clean/dry.

 A last question for you  Martin.
 What are you finishing the blades with? If oils, many change
 colors with a
 little time and in seconds if heated. Some waxes do the same
 but more
 slowly. These too are patinas and can be controlled to a
 degree in the shop
 but not in the customer's hands. Care needs to be taken with
 the final
 finish/sealant/rust preventative. For food I like bacon
 grease, culture
 permitting of course. Animal grease is a low toxicity,
 polymerization and
 color change finish.

 This is it. It is going through the Patina process. The heat
 speeds up the
 reaction tremendously. Glad to get to the bottom of this.
 Thanks guys.

  Salt, sauce, etc. will tarnish a
  polished blade. We call it "antiquing" when we want a
 patina. It will
 actually protect the blade. Dab some mustard  on it,
 let sit an hour or so
 and wash off; repeat until you  get the desired
 effect.
 "Mustardizing".

  Heat will speed up most chemical reactions
