i recently wheeled and dealed and came into the possession of several hundred (maybe more) fire bricks (from 3 round incinerators) that are slightly triangular in shape to make a round roughly 3' diameter circle, many are whole many are half's. all i wanted was
enough to make a Mass Rocket heater, But never look a
gift horse in the mouth
If anyone is passing thought North Central Arkansas and is in need of Fire Bricks PM me.
i'll try to get pics later
