Actually you'd better check back, unfortunately you got confused between the colour chart which is what needed to be regarded in 'diffused sunlight' and the steel itself which needed to be regarded in a 'dark or dimly lit room'.
Oh I made sure I was right before I posted that.... Don't worry about that.

We can be very cruel and obedient beings. It's in our nature, and unfortunately isn't unusual at all.

I disagree that it's in our nature, I think we are conditioned to except authority as the final word. We are conditioned this way in school, that's what school is for.
To learn obediance to ANY authority figure, to except and believe what authority tells us with no question.

Our natural desire to self rule is squashed by an instituation that puts young impressionable children in a very formal, controlled enviroment that children naturaly rebel against, until they are broken by fear of punishment or ridecule.

Some break sooner than others and become robots that wouldn't even think of questioning authority even when faced with obvious lies.

Some don't break at all and go to the extreme, as a reaction against authority, and become criminals or anarchists

In a balanced state where children are allowed to develope their own desire to learn without an authority (teachers etc.) forcing them to, then you wouldn't get either of the above IMO.

The image is of steel at a higher temperature than that being discussed... However...

In researching my case, I found evidence to see that you are correct - at even slightly less than 600 deg C the glow of the steel should be visible in Sunlight. It does not seem to agree with the chart and the wording that goes with it, but it's what it said never the less. Seeing as it was on a blacksmith's site and not connected with any of this it is more than likely accurate. He does actually reference another site as well if I remember rightly.

If you check back to the original thread you will find the information, and my.. apology
