Today I insulated the base of the oven with about 23 pounds of perlite and Portland cement. The ratio I used was 6 parts perlite to 1 part Portland and a appropriate amount of water to make a porridge like texture. Does anyone still eat porridge?
Because of the irregularities in the field stones, my oven chamber will not be as large as I hoped, but it still should be fine. The next step will be to lay out the firebrick floor and actually build the oven.

ReplyDeleteHow about gruel?
ReplyDeleteWhat's the difference between gruel and porride? We still eat porridge in our house.
ReplyDeleteAfter 15 seconds of research on the web, I learned that gruel is usually thinner than porridge.
