well you've just reminded me of something. Many many moons ago, when my father was in the Navy and came back from one of his long journeys, he my mother some solid perfumes, I think four in a long box or maybe three. I thought they were Japanese as a child, but perhaps they weren't, maybe French? They were treasured items, used sparingly, presumably strongly scented or something. They smelt gorgeous is all I recall

So perhaps your 'rouge' pot isn't far off.
