5. Firing the Bricks . Firing the Bricks. The final step in the brick making process was "cooking" the bricks in a kiln. The bricks had to be cooked to a high enough temperature to be "cured." Thousands of dry, raw bricks were stacked over a fire, and walls were built on all sides of the fire, to contain the high heat.

Using harsh chemicals can damage the bricks and mortar. Gentle and careful hand washing is recommended—using natural bristle brushes is fine, but avoid metal bristle brushes or Brillo pads because they will be too abrasive for old brick. The goal is not to make the brick look new but to reveal and preserve its aged beauty.

The abrasive medium, generally steel shot/grit, sand, or slag, is propelled through a hose by compressed air. The abrasive material abrades the surface of the structure, exposing the steel substrate underneath. The abrasive also conditions the substrate, forming a "profile" of the metal, which improves the adherence of the new paint.
