Not only is it expensive, but it is also more difficult to work with because it hardens way faster than standard Portland based mortars. Most oven builders use what we call "home brew" which has proved most suitable and quite cheap. The recipe is 3:1:1:1 fine sand, Portland cement, hydrated lime, bricklayers clay.
