The Chimney Safety Institute of America wants to show you some samples of creosote that were removed from the inner walls of a chimney. It's residue, a by-product of combustion – the substances produced when wood burns. [These include smoke, water vapor, gases, unburden wood particles, hydrocarbon, tar fog and assorted minerals. As these substances exit the fireplace or wood stove, and flow up into the relatively cooler chimney, condensation occurs.] Creosote is black or brown in appearance. It can be crusty and flaky…tar-like, drippy and sticky…or shiny and hardened.

We recommend having your chimney inspected at least once per year and swept as-needed. You can find a local CSIA Certified professional in your area www.csia.org/search.
