Dragon Skin

        The dragon skin method can be added to cups with a colored background and then a colored mica dusted over the top to add a shimmer or color shift.  A color shift will change colors as the cup is tilted different ways.   This method can be used to make a cup look like dragon skin or mermaid scales.   This method can also be added to the top of the cup to simulate something bubbling over, like a potion as seen on the dragon scale video.
