An elementary substance ,
not metallic in its nature ,
which is present in all organic compounds .
Atomic weight 11 .

Symbol C .
it is combustible ,
and forms the base of lampblack and charcoal ,
and enters largely into mineral coals .
In its pure crystallized state it constitutes the diamond ,
the hardest of known substances ,
occuring in monometric crystals like the octahedron ,
etc .
Another modification is graphite ,
or blacklead ,
and in this it is soft ,
and occurs in hexagonal prisms or tables .
When united with oxygen it forms carbon dioxide ,
commonly called carbonic acid ,
or carbonic oxide ,
according to the proportions of the oxygen ;
when united with hydrogen ,
it forms various compounds called hydrocarbons .

Diamond },
and {
Graphite }.

Compounds of carbon } (
Chem .),
those compounds consisting largely of carbon ,
commonly produced by animals and plants ,
and hence called organic compounds ,
though their synthesis may be effected in many cases in the laboratory .

carbon copy },
originally ,

{
Carbon light } (
Elec .),
an extremely brilliant electric light produced by passing a galvanic current through two carbon points kept constantly with their apexes neary in contact .
{
Carbon point } (
Elec .),
a small cylinder or bit of gas carbon moved forward by clockwork so that ,
as it is burned away by the electric current ,
it shall constantly maintain its proper relation to the opposing point .
{
Carbon paper },
a thin type of paper coated with a dark -
colored waxy substance which can be transferred to another sheet of paper underneath it by pressing on the carbon paper .
It is used by placing a sheet between two sheets of ordinary writing paper ,
and then writing or typing on the top sheet ,
by which process a copy of the writing or typing is transferred to the second sheet below ,
making a copy without the need for writing or typing a second time .
Multiple sheets may be used ,
with a carbon paper placed above each plain paper to which an impression is to be transferred .
In 1997 such paper was still used ,
particularly to make multiple copies of filled -
in purchase invoice forms ,
but in most applications this technique has been superseded by the more faithful xerographic reproduction and computerized printing processes .
{
Carbon tissue },
paper coated with gelatine and pigment ,
used in the autotype process of photography . --

{
Gas carbon },
a compact variety of carbon obtained as an incrustation on the interior of gas retorts ,
