I really like using the self-supporting cones when firing my kiln. They are very convenient to use. I always forget to make a cone pack with traditional cones so the self-supporting cones come in handy at the last minute. I feel they are very reliable when it comes to measuring the temperature inside a kiln when firing.
Perfect for testing 05 cone fire in kiln
These are excellent for firing clay in a kiln. No problems, works great!
