Mythological Story.

"Discovery of

fire”

It taught the existence of this type of

combustion to home erectus on the

impact on the ground burning

vegetation around.

The first method of ignition is

supposed that it was rubbing a tip of

dry stick on the same point of dry

wood.

It gave started to progress it would

breakthroughs; it was the source upon

which civilization was built. The fire

was used for cooking food for about s

1.9 million years ago,

although“Homo Erectus” not turned

it into an element of common use

until app. 400.000 years ago.

other combustible material is

combined with the air at sufficient

speed and thus produce light and

heat, along with ash, smoke and

vapors.

First Chimneys

They pick up stones to contain the

fire or simple reuse the same location

over and over again and allowing ash

acting as home.

Middle Paleolithic (c.a. Apr.

200.000-40.000 years ago).The heat

generated by the fire was used to

produce new chemical alterations:

food could be cooked and its color,

texture and taste changing. The mud

could cook in the form of bricks or

containers. And finally they could

make ceramics painted parts and even

glass objects.

Fuel

Hardwoods such as oak for soft pine

wood burning.

If the wood was not available use of

alternative fuels such as peat, turf,

animal manure, animal brave,

seaweed, straw and hay, which can be

used in a fire. Animal manure was

probably used, but not constantly

until after the domestication of

animals which led to save the

livestock about 10.000 years ago.

The Lamp

Year 50.000 B. C. The earliest forms of light were

burning sticks or containers full of

embers then used torches formed by

bundles of branches or resinous wood

chips, tied and soaked in tallow or oil

to improve their combustion qualities.

The oil lamp was oil liquid containers

that were burning through a wick.
