Question

please tell me about uses of fire

Answer 1

Coppicing basket materials
Clearing brush for ease of travel and hunting 
Removing thatch in late fall to promote wildflower seeds and bulbs for food 
Burning meadows in summer to promote seed bearing grasses (weeding and fertilizing) 
General burning to revitalize plant communities for greater abundance 
Clear ground for food gathering

Hunting

Drive grasshoppers into cooking pit
Drive ground squirrels from holes
Smoke bees from hive
Chase bison and other game over cliff or into trap
Night fishing with torch

Cooking

Roasting on coals or grill
Baking in pit or stone oven
Indirect cooking - as planking salmon 
Boiling in clay pot or stone boiling in basket or wooden bowl, etc. 
Parching seeds

Steam bending wood

Straighten arrow, dart and spear shafts
Recurve and reflex bows
Bend basket rim sticks
Bend looped stirring sticks for stone boiling
Straighten hand drills for fire making

Smoking hides and meat to preserve

Softening tar and pitch for adhesive

Heat treating stone for tools

Wood working

Burn bowls and spoons
Dugout canoes
Burning down trees 
Sharpening and fire hardening digging sticks and spears 
General burn and scrape shaping

Making charcoal

For cooking and heating
For smelting metals
For firing pottery
For blacksmithing and metal casting
For pigment 
For medicine and water purification

Charring to preserve house posts from insects and rot

Smudge fires to repel mosquitoes

Fire to repel predators

Heating shelters, etc.

Lighting (torches)

Smoking tobacco and medicines

Cauterizing wounds

Communication - signaling

Steaming

To extract agave fibers 
To soften bone and wood for working

Ceremonies - uses too numerous to list

 



The listing above is limited to what I could think of sitting at my computer. I'm sure I've left out many other applications of one of our most basic tools - including most modern industrial uses such as generating the electricity that runs my PC. Most anthropologists would agree that the ability to use fire and make tools were what separated us from our earlier ancestors and made us human. Both require memory and advanced planning to be effective. Perhaps the most profound of these uses of fire, and the ones I listed first, are the ways early humans used it to modify the landscape to provide an easier life. Generations of observing accidental burns led most of the world's groups to understand the optimal pattern of burning to maximize valuable food resources.

In California, burning right after the harvest of the largest grass seeds in the summer eliminated shrubs and those species which had not yet set seed, and turned the dead thatch from one years growth into fertilizer for the next. Harvesting techniques were inefficient enough to provide seed. Over time, whole meadows became stands of the food producing grass. Burning the hills just before the winter rains gave a head start to wildflowers and opened up the ground to sunlight. This also favors the growth of bulbs. The two foods that were served to the Spanish explorers near San Francisco Bay were seed cakes from Red Maids and the bulbs called brodeias. Without fire, Red Maids are rather rare today.

Answer 2

Fire is a dangerous thing. It is using for to burn some dust things like papers plastics etc. Fire is using for make food like something etc.
