Yes, you can hand-pull your own stringers using a Vitrigraph kiln. If you have the opportunity to use a Vitrigraph kiln, we highly recommend you take it. Not only is it fun, but you will be able to make unusually shaped stringers that can be used to create interesting and unique imagery.
To read about the process and equipment needed, see TechNote 2: The Vitrigraph Kiln . Our online education program includes a lesson on the Vitrigraph kiln, and we offer demonstrations frequently in our Resource Centers.
