Before a stick is burnt, several observations can be made, including:
-
Material Properties: The stick's texture, color, and moisture content can be noted. Is it dry or wet? Is it made of hardwood or softwood?
-
Size and Shape: The length, diameter, and overall shape of the stick can be observed. Is it straight or bent? Are there any knots or irregularities?
-
Environmental Conditions: The surrounding environment can be noted—temperature, humidity, wind conditions, and the presence of other flammable materials.
-
Surface Condition: The surface may show signs of decay, bark presence, or insects. Is it smooth or rough to the touch?
-
Smell: Freshwood may have a distinct scent, while older wood might smell musty or of mold.
-
Sound: When handled or struck against another object, the sound it produces can hint at the stick's density and moisture content.
-
Previous Uses: If the stick has been used before (as a walking stick, tool, etc.), any signs like wear, cuts, or marks can be observed.
-
Placement: The position of the stick can indicate how it might behave during combustion (e.g., Is it on a flat surface, surrounded by kindling, or isolated?).
These observations can provide insights into how the stick may burn, such as how quickly it will ignite and how long it might last while burning.
