I did my first electric kiln firing today. I'm using a downdraft system (Envrionvent 2 with Skutt Cone 10 kiln). It specifically says to fire with all the peep hole plugs in but I mistakenly left out
the top peep hole plug. I'm worried this may not "prime" the kiln correctly or may have some other negative effect.
Please, those of you who know technically about firing, could you let me know if this is a problem? Everything seemed to go ok. Took about 8 hours to reach cone 04 on medium speed setting.
