Studio Pottery Slab Votive Holder w/Embossed Thistles - Amaranth Canada. This is a very unique handmade piece. I'm calling it a candle holder because that is my guess. It is made of cement and has an embossed thistle flower pattern. There is an indented portion which is about 2 in wide in one corner and it is filled with resin and chips of glass. I'm assuming that a votive holder goes there, but you could use your imagination. I've never seen anything quite like this
