How do i know if i over heated my base?
So i was giving my custom x a hot wax last night and was getting the base nice and warm to get the wax to absorb good. I always kept the iron moving and everything and i felt the base just after and it was pretty warm, not hot though. I got wondering how i tell if i over heated my base, i'm 90% sure i didn't becuase i read somewhere that said it won't happen until about 140* C which my iron won't even go to. But now i'm just curious, what are the signs of an over heated base, i couldn't find anything on here or the internet, just that when your waxing you can't stop the iron for to long or it will happen.
