Tar-like residue from incomplete wood combustion. Highly flammable.
The black, sticky-to-glassy substance that builds up inside a chimney flue when wood smoke condenses on cool walls. Stage 1 is dust, Stage 2 is crunchy, Stage 3 is hard glaze — and Stage 3 is what causes most chimney fires. Annual sweeping removes Stages 1–2; restoration removes Stage 3.
