The media used is Honeycomb Calcite from Utah and Flagstone chosen from local landscape companies. They have a glass bowl glued on the bottom ,2 holes drilled (1 for wick and 1 to fill the bowl). This is easier than pulling messy wick and reinserting it. We have been making candles for about 15 years and our designs have changed over the years. Our newest candle is called a "Stacked" candle. We put a larger slab on the bottom and glue a smaller slab on top, creating a beautiful candle. On each of these candles a cylinder can be added to create a beautiful golden glow.
