Two shelf firing
I have a Jen Ken kiln at home and a selection of Skutts at the studio I teach at.
I have (when rushed trying to get ready for a show fired two shelves, hard to do in a shallow kiln, the top had pendant blocks that needed a full fuse and the bottom where fire polish, it worked out really well, but I know my kiln. I know how hot she runs and when to push her. The Skutts we load up when firing pottery with plates under bowls and cups in the bowls as long as it does not have glaze on it.
