Leveling insulation

Here I am leveling off the insulation. I did amazingly well on my guess as to how much slip and how much perlite I needed. I used about one bucket of slip (about 3.5 - 4 gallons) that was about the thickness of pancake batter and four bags of perlite (5 dry quarts each) from the garden center. I poured the slip through a sieve of hardware cloth to get the gravel out but I am not sure this was necessary. The mix looked something like oatmeal cookies when it was done. This will sit over night to cure a bit.
