Many people leave it up to luck, fate, or "Kiln gods" when firing out work.  But once you get to know your kiln, you can use it to add a whole new layer of interest to your work by how you choose to fire it. Even when electric firing, using different firing schedules, holds, cooling techniques, and much more can make your pots more exciting to create and enjoy. So be brave, put some shelf cones in your kilns, and try a few things.  I talk slowly in the podcast to explain things clearly, but I might have done a lousy job.
