Kiln Fire This kiln at Renaissance Hall requires a team of experienced wood firers. Art students participating in the firing of their work sign up for two-hour slots, working with an experienced firing crew member. Wood is stoked into the kiln around the clock for four days, ending with a final larger stoke at the end. The kiln cools for at least ten days before opening and inspecting the new work. Every kiln opening is like Christmas as a kid when the unwrapping of presents begins.
