To create the color swirl effect, the colored glass frit is applied directly to the piece, rather than to a wrap. Whereas the wrap stretches the melted colors into that sweeping movement, the directly applied frit initially looks like colored dots. However, once softened, a sort of finger-painting method is used to create movement in those dots with the use of various tools.
Additionally, there is no solid opaque background. Instead, a thin layer of a very fine, neutral opaque frit is applied just before the main colors just to add a little character. Antique bulbs work exceptionally well with these shades.
