You may not know that white tealight candles are made by pressing machines which press wax beads into tealight. Good quality tealight candles should be dense in structure and not easy to crumble. The trick is with the size of wax beads and the working pressure of candle pressing machines. Our wax bead spray drum can adjust the diameter of wax beads when the wax changes to give you the best quality tealight candles.
