Ok seems I must make it out of clay, not brick. Also my next dilemma. I spoke with the professor of geology at a local university and he told me I won't find any rocks with more than 10% iron in my area. Would this be a waste to smelt?

Hi everyone, I'm new here. So I want to smelt Iron. I know the principles, however I am having trouble with the furnace. I have red clay bricks, portland cement, powdered lime, sand, and fire clay (powdered.) Does anyone know what mixture to use to make mortar for use in my furnace? also any help with design would be very welcomed.
