Tempilaq
Gentlemen,has anybody used 'Tempilaq" when annealing cases,does it work? how hot does the brass have to be? to anneal,thanks in advance!

How hot
Bambay club,
As I understand it, Tempilaq is a tell tale. You buy the Tempilaq by temperature rating and when you heat the material it has been applied to, to the temperature the stuff if is rated for, the Tempilaq melts and you're there. What you are looking for is about a 675 degree stick. The critical temperature for annealing brass is somewhere between about 650 and 675 degrees. Anything more is a waste of heat and anything greatly more, such a getting to the point of incandescence, can make the brass way, way too soft. Good luck.

Troll,
For non-ferrous materials water quench softens. In my opinion, air cooling is just as good as a cold water quench, it just isn't as fast, if time is a concern.

Temperature sensitive crayons
I am a relative newcomer to the annealing process. I bought a couple of temperature sensitive crayons from McMaster-Carr and they work very well in the annealing process. They are available in different temperature ranges. The ones I bought are for 650 degrees.
I ordered them online one afternoon and they were on my doorstep the next afternoon. I also purchased a Lee lock stud and shellholder for my caliber and slowly spin the cases with a cordless drill while I'm annealing.
It works great.

Bombay club,
My understanding of annealing brass is that the heating does the annealing, or softening, and the means of cooling have little effect on that process. Water cooling will prevent excess heat from migrating to unwanted areas such as the case head where softening is not good. Generally the amount of heat correctly applied to the mouth of the case is insufficient to anneal the head, so air cooling works too. I water cool mine only because the water cushions the fall when I drop the cases and I don't have to be careful where I set them. Good luck
ps, McMaster Carr has proved to be an excellent company to trade with. Their service is fantastic.

Saul,
I know shooters that anneal every time and then I have me and I anneal about every 5th firing. Probably going to have to redo some cases by the end of the summer for the 45-90. I do not anneal the cases used for paper patching. Last summer Steve Witt shot that 98/100 using freshly annealed cses. At least we have an idea that it doesn't hurt anything.
