Take a piece of rod and heat it up to form a ball on the end. Hold the ball straight up and down and slowly and gently push it into a "Maria" (Disc) on your marver. Pinch the maria all the way around with some needle nose pliers.
Then reheat and slowly pull it in an upward angle one pinch at a time. Reheat as much as you need to perform the task. Do not overheat the glass. This will form a very nice bell flower. After pulling it off the main rod, you can nip the end off to make a hole at the base end of the flower, if you want it to be used as a bead The flowers on the base in the photos were only pinched 4 times, 6 will make a better bell flower version. (I ground the horizontal tooling off of the inside of the pliers and then cut some length wise groves in them to make a more interesting flower.)
I also cast a two part mold from aluminum for my press, but it is just as easy to pinch them out.
Various size rods equals various size flowers. I may do a video tutorial on this one.
