Annealing with a thermal imaging scanner

[killer_penguin]

This is probably the coolest method of setting up annealing temperature that I've seen yet.

You're right. It looks neat. But it isn't as accurate as using the temp-lac paint sticks.

Can you elaborate as to why?

Re: Annealing with a thermal imaging scanner

Don't take my word for it. Do some back ground on it. The visual units that were in the shops where I worked in the 1990s weren't as accurate as the temp sticks. The state of the art has changed, I'm sure. But personally I can't afford state of the art. The ones most people can afford are several generations behind. Like the one's I was using for the government in the 1990s. I left the shops in 2001. Do some research. Don't take my word for it. I'm old as are most of my toys. Burn a little midnight oil and see what's what for yourself.

Here ya go, i think this is what you are eluding to.

Also, note they're spot-checking the brass once it's in a stable position out of the flame. It's temperature at that point is quite a bit lower than when being annealed in the flame, which is what they're trying to determine.

+1 on the temp-lac paint sticks. Some things do not get better by adding buttons and switches and a color monitor.

it's just a video of what an annealer looks like through thermal imaging
