I also think it looks great and that lather!! Remember also that as it ages, that dark circle will fade out a lot. With the cute stamp you've used and fading, customers won't think anything is amiss. It looks like a really gentle, creamy soap. NIce one!
I always freeze my GM logs for a few hours after I make them. And I rinse and freeze the wood surrounding the silicone mold before I pour in the mix also, just to make certain no partial gel happens! Might be easier to stop gel completely next time on this rather than try to gauge the right temp to do a full gel w/o a volcano?
Either way, it looks and works great!
