It’s been two years that I’ve made this ceramic diffuser. The top of the castle can be filled with water and scented oil. And when you place a candle inside the castle the heat of the candle makes the scented oil to evaporate. It took sixteen hours to make it, even with the help of my teacher Nedoglou Stella, who I thank greatly! The colors are her advice and I couldn’t be happier with the way it turned out.
