When I started wetshaving a few weeks ago, the first soap I bought was AOS Lavender in the beautiful (but useless) wooden bowl. Whilst I really like this soap, I don't often use it as it's messy as hell to work up a bit of lather on the top - even for transferring to a bowl.
Anyway I knocked the cake out of the wooden bowl and have been searching for something nice to put it in. I managed to buy this cool Old Spice 1960's shaving mug on Ebay yesterday for not much money.
Ideally when it arrives, I'd like to melt the AOS Lavender cake so it bonds and forms to the bottom of the mug. Can I just warm it in the microwave like with Mama-Bear soaps, or is it a vastly different formulation which will be damaged in my microwave?
If so, any other ways to melt it? I was wondering if placing the cake in the bowl and then floating the bowl in boiling/simmering water until the cake melts would do the trick?
Obviously I don't want to ruin a nice and expensive puck of soap!
