Tempil 24423- TEMPILAQ Advanced TL060 Temperature Indicating Liquid, 399 Degree C/750 Degree F, 2 oz.Ideal for Heat Treating, Brass Annealing, and Glass Production, Made in USA

Works as advertised.

I use it to set the time required for properly annealing case necks. Paint it inside the neck and let it dry. Once in the annealer it will go to liquid as soon as temp is reached. Once the settings are correct I make the run. Only a little is needed for the set up. The bottle will last a long time for this purpose. Make sure to shake it well to mix it before applying.

I use the 700 and 750 degree TEMPILAQ to adjust the flame and rotational speed of my Annealeez brass cartridge annealing machine to achieve the ideal temperature range. Serious reloaders know that cartridge brass work-hardens with each reloading/firing cycle. Hard brass splits and lacks consistency. Annealing returns the brass to factory new ductile condition, and can be done many times. The "magic" is knowing exactly the right temperature and time so brass isn't over annealed, burned, or "just warmed' without any true softening. This paint works GREAT - but it always dries up in the bottle before it is used up (regardless of tightening the lid and storing in another air-tight container). I may try the pens next - although more expensive per oz of paint, they may actually last longer.

I like that it changes colors when at temperature. Using it to reach the correct temperature when setting up my Ugly Annealer for rifle brass. Sacrificed a couple pieces of old range brass as an experiment. Hint I put a line on the neck and three more places going back to make sure I wasn’t heating my brass to far back on the case!

I have been annealing my brass at a buddy's house for a few months and we use Tempilaq (specifically TL060) to gauge when the brass is properly annealed. It's very simple: swab a little on the inside of the neck and run it through your annealer. (My video is done with the AGS Annealer.) It doesn't get any simpler than that. This stuff is a must for consistent annealing!

When annealing brass its important to know when the proper temperature has been reached so that the brass isn't destroyed by guessing.

It was useful for what I needed it for. I tightened the top well but still was mostly dry when I needed it again. So, give the top an extra hard twist.

Worked exactly as advertised and was easier than I expected.

Just what I needed to gauge heating time for annealing brass. As advertised. Easy to use.

Great product, fast shipping.

Used it to try to judge how much to heat my 7mm rm brass. Used it on two pieces of brass to get the idea what I was looking for as I was using a drill 5/8 spark plug socket ( I think that was the size) and a propane torch. Found if I turned the lights off I could judge well enough without it ( light red ) and repeat.

Great product for brass annealing set up to make sure your temperature is in the correct zone.

The produce works great the application I'musing it in.
