Creosote is a flammable and corrosive substance that accumulates on the walls of fireplaces and chimneys. It is created after wood particles, fly ash and other gases mix together on their way out of your home. If your chimney isn’t clean or properly ventilated, creosote will build up on the walls. As the build-up continues to accumulate, it can cause a chimney fire.
How is Creosote Formed?
Creosote is formed through:
- Condensation: If you cut down on the amount of air entering the chamber so that your fire smolders, this leads to flue gas condensing on the inside of your chimney and turns the resin into creosote.
- Liquidation: The resin or sap will turn liquid and enter mortar joints and cracks in your chimney.
- Solidification: As the temperature fluctuates inside of your chimney, the build-up will accelerate as the space in the chimney decreases and gas struggles to get out.
Once creosote is formed, it will go through three stages:
- Flaky soot that is easy to remove
- Hard and shiny black flakes containing tar
- A tar-like coating all over the inside of your chimney that is hard and extremely flammable
How Can You Minimize Creosote?
It is always best to prevent creosote build-up through smart daily chimney practices instead of needing to scrape away caked-on layers. To minimize creosote:
- Don’t burn slow or smoldering fires in your fireplace
- Never burn unseasoned wood that was cut within the last 6 months-1 year
- Never burn artificial logs in your fireplace
- Burn hot fires with plenty of air
