  1. Hello! I have a question regarding what cones my kiln is able to fire to. I’m using a manual skutt 1227 that hasn’t been used in approximately 4yrs. I am a school teacher and have been told this kiln has been at the school since 1996. I have successfully fired the kiln up to cone 04 with low fire clay and glazes. Today I tried to fire some cone 6 clay/glazes, but after about 9.5 hrs on high the kiln still had not reached cone 6 temps. Could this be a problem of needing new elements? Or something more complex?
  2. I have been trying to be scientific about arranging my firing schedule in a small electric kiln with a controller. I understand the concept of heatwork and use cones on all shelves in my kiln to monitor results. I soak at top temperature and fire down so want to compensate for the additional heatwork these procedures involve when I set the top temperature on my controller. I understood that this could be done by looking at the area under a graph of total heatwork, but having compared theoretical models using the Orton cone firing tables, if this is indeed the case, I must be missing somethin
