I have tried different waxes on my hand

those from regular table candles is not so bad and I tried it on my
areolas after having had some on my hand

I tried wax from these light one use for "tea stoves", don't know the
english term, and that was much hotter. (i.e. only tried it in my hand)
You see its getting liquid inside the form and hotter then still.

Bee wax is very hot when melted. I had some in my hand ones.
I guess that was enough for me

Ok, that might not be an expert-opinion, but then you can
rely on it's truth
