Pine tendds to burn very quickly. The exact time will depend on the size of the log, and how dry it is.
Green is not a species of wood- it just means recently cut wood that still contains much of the moisture and sap of the living tree. When cured (means dried) it will burn much better. Cured Oak is among the best firewood for heat.
Is there anything can appy to make pine wood burn in the fire place
yes
pine wood burns very rapidly because it is not dense and is full of very flammable rosin.
Dry, seasoned and resinous pine wood burns fastest.
Avocado wood (and any natural wood) will burn. Heat value is similar to elm. More heat value than pine, less than oak.
Hot enough to burn wood.
Is it toxic? No- no more than any other wood- but pine will burn very quickly, and produce high levels of creosote in the chimney.
With a magnifying glass
One way for a fire to burn at a different temperature is it's wood soft wood such as pine burn fast and hot but hard wood such as muscle wood burns slower and cooler but still hot enough to burn you so don't touch it
Soft wood...
The wood in a match can burn at temperatures exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit).
