Thank you. The ones on the far right really are kneeling. 'Candle holder' is 'kynttilänjalka' in Finnish which literally means 'candle foot' so making holders with actual feet is a practical pun. Because of the kneeling pose people have called them "proposal candle holders".
These were not cast but forged. The hammer marks are there because that's what they were made with.
The surface is tar-burned to black but I could also have polished them with wax afterwards. Burning with tar or oil is a traditional way to do finishing to forged items so I scarcely use black paint.
