The combustion process creates noxious gases that can contain creosote/soot, carbon monoxide and corrosive chemicals. The purpose of your chimney is to safely vent these hazardous flue gases from your home. Flue tiles are typically sealed with mortar to keep these gases within the flue. But over time, the mixture of heat, moisture and chemicals will erode the mortar, leaving gaps or voids between flue tiles.

Flaking Flue Tiles (Spalling)
Years of exposure to corrosive chemicals and moisture from combustion can attack clay flue tiles, causing pieces of the flue liner to flake off or delaminate, a process called spalling.
