Tempil 24421 TEMPILAQ Advanced TL060 Temperature Indicating Liquid, 343 Degree C/650 Degree F, 2 oz.Ideal for Heat Treating, Brass Annealing, and Glass production, Made in USA

I use the 750 and 650 for annealing brass and it is critical that the temperature is correct. this product is well worth the price. the 450 is to ensure the temperature does not overheat the lower half of the brass.

Great product fast shipping

Began annealing brass and this was what I needed to make sure I’m getting the temperature I need. This bottles gonna last a very long time. Worth it

Useful for determining temp/flame applied on my brass.

Expensive but hard to find. Works as supposed to.

Great for monitoring temperature when annealing cartridges. It is easy to use and changes color when the temperature reaches the limit specified in the product label.

Junk! It's my fault for not checking it upon arrival. I just put in the reloading room and waited 3 weeks for my annealer to arrive. When I opened the bottle it was a chunky, congealed mess. The bottle threads and brush stem were thick with dried paint. Old? Used? Improperly sealed? Who knows, but no amount of shaking would reconstitute this hot mess. I even slowly added some thinner in a weak attempt at doing a quick set up, but to no avail. I know a lot of people like this stuff, I wish I could give a better review.

excellent product. will purchase again.

Totally satisfied,thank you.

FAIR DEAL.
