Natural Materials:
* Wood: Logs, lumber, sawdust, wood chips, paper, cardboard
* Plants: Grass, leaves, hay, straw, cotton
* Textiles: Cotton, wool, silk, linen
* Leather: Animal hides
* Rubber: Natural rubber from trees
* Coal: Bituminous, anthracite, lignite
* Peat: Partially decayed plant matter
Processed Materials:
* Plastics: Polyethylene, polypropylene, polystyrene, PVC
* Rubber: Synthetic rubber
* Paper: Newsprint, book paper, packaging paper
* Textiles: Synthetic fabrics (nylon, polyester, acrylic)
* Wood Products: Plywood, MDF, particleboard
* Composites: Fiberglass, carbon fiber, wood-plastic composites
Other:
* Fuel Briquettes: Compressed wood, coal, or biomass
* Charcoal: Partially burned wood
* Propane Tanks: Although technically a gas, the tank itself is a solid combustible material.
* Tires: Made from rubber and other materials.
Important Note: The flammability and burning characteristics of solid combustible materials vary greatly depending on factors like:
* Chemical Composition: The chemical makeup determines how easily a material will ignite and burn.
* Moisture Content: Dry materials ignite more easily than moist materials.
* Size and Shape: Smaller pieces of material burn faster than larger pieces.
* Density: Dense materials tend to burn slower than less dense materials.
* Presence of Oxygen: Combustion requires oxygen.
It's important to understand the properties of the materials you are working with to prevent fire hazards and ensure safety.
