These would be perfect for adorning a deep dungeon, adding a level of atmosphere to their heroic crawling looking for loot. They could also add a lot more fire to a piece of terrain. I imagine that skull filled brazier would work well for adding to a temple to make it more chaotic.
Even in historical gaming the deeper coal pan on the left would be great for outside a religious structure, maybe even the fires burning beneath an oracles gaze.
Will you be picking these up?
