Annealing-What Temp?

I am going to be doing some testing and I am going to order a few temperature indicating items, either laquer or a wax type pen.

I just need to know what temperature annealing brass occurs so I can run a bead ot the sensing agent down the side of a case to make sure there isn't too much heat making it to far down the case when testing a new idea.

Hornady sells a kit that says 475 degrees on it for $50 or so dollars. I can get the same laquer for $14 but I just want to make sure I get the right temp.

Here is the cheaper laquer methods from McMaster-Carr.

Thanks
