The "Raden Spiral" fountain pen is a cylinder shaped, fullsize, clipless ebonite fountain pen, featuring a stunningpattern of colors made of "Raden" (=mother of pearl) and urushi with powdergold. It is a cartridge converter pen with a Nr. 6 two tone nib. The pen has been covered in black base urushi lacquer (wet sanded with #1000 grid sandpaper after each application and curing). Then raden pieces where attached in a spiral patterns, then layers of clear urushi and powder gold in stripes. The next layers where done with clear urushi, until the pen seemed to be almost black - brown in color. Once the urushi was completey cured, the pen was wet sanded until the raden became visible and the gilding showed through depending on the thickness of the lacquer. For the finishing kijo-mi urushi got applicated on the pen and wiped off with filtering paper. After a final curing period the lacquer was burnished and polished several times to a glasslike shine. Length of the production process: 3 months.
