A simple old school method to test for how high the kilns are firing the bent cone is firing higher (06) and the other didn't (07). You can also put three cones in the bottom of the kiln, or middle and at the top, especially helpful for using gas firing. This way you can see where it's hotter to better distribute the flame. Bet you didn't know that!! https://www.instagram.com/p/CqKS4UouCLS/?igshid=NGJjMDIxMWI=
