how hot is too hot for drying brass?

[Grawfr]

If I can't wait a couple days at room temperature on a window sill, I put it a couple hours in the oven at min temp, about 150F. If the temp is too low to boil water, I doubt it's going to affect the brass' hardness in two hours.

Don't ask me how I know but I'll take a WAG and say 160 degrees.

I wouldn't say "specifically designed' considering with exception to the color of the plastic it is exactly the same as my 15 year old Nesco food dehydrator. It's a great rebranded item for our purposes though.

Edit... here's the exact one I paid $60 for and use to dry my brass.
