268688 scott grandstaff <scottg@s...> 2019‑06‑15 temper colors
I got a score on heavy gauge stainless vent pipe one time, and it fit 
my stove, so I took it years ago. It's good pipe, I'll never wear this 
stuff out.

Anyway it has the most perfect temper rainbow I ever saw. Its so 
exaggerated!!
  So, right in the middle? The pure stainless steel look? That is what 
you never want to see, lol.
That's steel that has been heated past any temper.

But if you go to the outsides of the rainbow? The place where it barely 
starts? Right at the top of the screen and actually a little above? 
Pretty close to plain steel looking, but some beginning hint of greasy 
yellow?
  That's what I shoot for when making a cutting tool. A knife or blade 
for a tool.
Can barely see it at all.
If you can make it out clearly you went a little too far.
  But its not a hanging matter. Its still a good edge.

Then you got your actual greasy yellow. Outdoor tools of a cutting 
nature. Takes a good edge but not as good as it holds that edge. Good 
wearing in other words. Machete.

Below that is darkening and heading towards purple.
  Screwdriver tips and suchlike. Where edge is not the thing but 
toughness is.

  After that brown spots in hard purple.
Shovels and ground engagement tools where toughness in brutal use is 
even more important that holding a shaving edge.

  Last...... spring blue.  All springs are this color unless they polish 
it off after.

Anyway I thought it was a cool picture
    yours Scott

Never mind the pipe - look at that moulding behind.  

Split turnings with swags, dentil insets.  Nice work!
