There are two ways by which you can do this.The first way is by pouring hot water into the ceramic candle holder. The wax will melt and rise to the surface. Once the water has cooled, pour the water out and ease the wax out of the ceramic candle holder.The second way is to place the ceramic candle holder in your freezer and leave it there overnight. Freezing will cause the wax to shrink. The next morning, all you need to do is flip the ceramic candle holder upside down, and the wax should pop out.For both, we recommend washing any remnants of wax out with hot, soapy water, before either reusing or refilling your beautiful, handmade vessel.
