factor number of vanes wanted, divided by 360 degrees = angle of set up. Stand the blades of glass on end and put in a circle inside of a kiln, separating the blades of color by the angle of set up. Preheat to 1100 F, blow a ball on the end of the pipe, open the ball creating a glass rondelle with a hole up through the center - through the pipe. Heat face of rondelle and go straight down on top of preheated colored glass plates. Allow to stiffen, re heat the entire thing, gather more glass over everything, vacuum the end of the pipe pulling all air out of gather. Add more clear glass from the crucible. Pull cane and anneal. Break into small pieces and make marbles from there.
