Book of 25 sheets. Palladium is silver coloured but does not burn off like silver leaf. Apply your Palladium leaf to the surface of the bead and then work in a hot neutral fame. The Palladium leaf will change to a metallic iridescent blues, greens and purples. Low temperatures could see it produce teals and purples. Before putting your bead in the kiln, soak the bead in a hot flame for a few seconds and then allow it to cool. The heating and cooling plus annealing will bring out those beautiful iridescent colours.
