This technique requires a skilled artist with a steady hand. Parallel lines of color are first melted and twisted into a vessel. The artist then re-opens the vessel and melts in another set of parallel lines. The second set of lines is twisted in the opposite direction leaving a cross-spiral design embedded in the glass. The fillacello effect in essence, is created by painting with molten glass, using a molten boro rod which helps achieve the refined color work which is found on this type of glass spoon pipes.
