The materials used for a traditional firelog are variable, the sawdust used is often commercial wood waste from manufacturers, or waste agricultural biomass (nut shells, fruit pits, etc.); additionally bio-wax may be used in lieu of paraffin (petroleum-based wax). There are wood and wax firelogs made using renewable materials.
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]
Using paraffin wax as a fuel has two advantages. First, when the burner cools the wax hardens making it convenient to keep in the burner for later use. Second, it is safe to refuel the burner while it is operating since placing solid paraffin wax on top of the burning stove involves no danger of the fresh fuel igniting explosively.
A briquette (French:; also spelled briquet) is a compressed block of coal dust [1] or other combustible biomass material (e.g. charcoal, sawdust, wood chips, [2] peat, or paper) used for fuel and kindling to start a fire. The term is a diminutive derived from the French word brique, meaning brick.
Keeping the air flowing correctly through a wood-burning stove is essential for safe and efficient operation of the stove. Fresh air needs to enter the firebox to provide oxygen for the fire; as the fire burns, the smoke must be allowed to rise through the stove pipe, creating negative pressure in the firebox, and exit through the chimney.
Fire making, fire lighting or fire craft is the process of artificially starting a fire. It requires completing the fire triangle , usually by heating tinder above its autoignition temperature . Fire is an essential tool for human survival and the use of fire was important in early human cultural history since the Lower Paleolithic .
Wax bullets can be easily constructed by using a cartridge case to punch a cylinder out of a sheet of paraffin wax, and then priming the cartridge using normal handloading equipment. The optional addition of beeswax and/or grease will produce a softer, more flexible bullet than pure paraffin.
Wax emulsions based on beeswax, carnauba wax and paraffin wax are used in creams and ointments. The emergence of soybean waxes with varying properties and melt points has led to the use of vegetable wax emulsions in applications such as paper coatings, paint and ink additives, and even wet sizing for pulp and paper applications.
