The crude iron is run at once into an oval pit, orbasin, in sand; the cinder is cleared off, and water is sprinkled over the yet liquid metal to chill this way, plate after plate, weighing from 25 to 50 lbs. each, is formed in intervals of hardly a gray iron, from fusible materials, will chill in this way. The plates thus made are roasted, i. for 10 or 12 hours to a red-heat, either in an appropriate oven or in an open pile; by whichthey are slowly decarburated. If this operation of roasting were in any case well performed, a greatdeal of the carbon should be got rid of; but the expense of fuel is very considerable. 2398. ^5,.
