I am a high school ceramics teacher (this is my first year doing ceramics in 6 years after a transfer within my district) so I am relearning everything about ceramcis, and kiln firing is very new for me. The school has a Geil gas kiln. I am (attempting) cone 10 reduction firing and I can not get Vegas Red to come out red. One piece came out transparent (middlish-front of the kiln). There were a couple that were towards the bottom back of the kiln that had some red come out. I am following a schedule I found in a notebook from the previous teacher. It fires around 12 hours. The glaze is the premixed glaze from aardvark.
I hope this is enough information to help me out I am not sure if I am getting into reduction properly or not. Any help would be great, if I need to provide more information please let me know. Like I said this is new for me and trying to figure it all out.
