Ive read and watched videos, but seems there is a lot of variation and advice. I am using a propane tank as my shell. I will line it with two 1" layers of ceramic wool. I have read to coat the first layer of wool and heat, then do the same for the second layer of wool. Yes or no to this and why? Will be using KOL 30 for the coating at approx 3/8". If yes to coating both layers of wool, would I do a thinner coat on the first layer?
My other question is what to use for the floor. I am leaning towards kiln shelf/alumina. do I just sit this on top of my wool that has been coated in KOL 30, set it on top of the coated wool and then coat the kiln shelf, or set it on top of uncoated wool and coat the wool and kiln shelf together?
