This is a style that was a part of the first wave in innovation of coloring techniques. After the Wrap n rake style a new style called inside out started. Unlike the wrap n rake technique where color is added to the surface, inside outs actually have color added to the inside. The artist opens up a tube of clear glass and draws on the inside, then closes the tube back up to shape the piece. Many have considered these “double or triple blown”. This phrase is a bit of a made up term to try to describe the thickness and the visual effect created by the inside out technique. These pieces tend to have some incredible color changing effects and have a beautiful depth in their design.
