My 36" oven has been sitting fro 8 days now and I was going to do the first fire in a couple days. As of now i don't have any insulation on the outside of the dome, just a coating of fireclay and portland cement mixture over the firebicks. My plan is to enclose the strucuture, put 1" cermaic blanket and then fill it with 6-6" of perlite. Should I do this before I start curing the oven? I would prefer to wait incase i have any cracks or issues.
