Fired Bricks . The ancient Persians and Assyrians made stronger bricks by roasting them in kilns. The process takes several days, raising the temperature above 1000 °C for a day or so, then cooling gradually. (This is much hotter than the mild roasting or calcination used to make top dressing for baseball fields.) The Romans advanced the ...
