I melted some of her Aged Spice into a Old Spice Mug that I use every day. It didn't lose any scent.
For the sample chips I tuck the chip, in its envelope, under my arm for a few minutes (yea, the pits ) then I just mash the chip into the bottom of a lather bowl with my thumbs. It mashes pretty easily from 97F.

It is very likely that there could be a great difference between melting the soap with a microwave and a double burner. I've never nuked any soap but the double burner works great.
I don't bring the water up to a boil, just get it warm enough to melt the soap.
