Composition Of Bricks

bricks should contain a little amount of finely powdered lime. it enables silica (of a required portion) to melt at the furnace temperature of 1650 o c and binds the particles of brick together resulting in strong and durable bricks. at about 1100 o c, lime acts as a catalyst to elevate the furnace temperature to 1650 o c at which silica fuses..the ironstone mines of shropshire,the proportion was 1:10. thus in that year about 5.5 million tons of shale were picked over. shale with ironstone coal however, investigations are currently being made to assess the safety of these areas, as some voids in part the miners had built brick arch supports..the geology of bricks,second, what if an actual fire could bake the right kind of sandy shale? in fact, that does happen in coal country. forest fires can start coal beds burning, and once started these coal-seam fires may go on for centuries. sure enough, shale overlying coal fires can turn into a red clinkery rock that's close enough to true brick.
