When Mustang performs his flame alchemy, he doesn't clap his hands to create
it, did he? He's only snapping his fingers:

The others seem to always clap when performing alchemy:

How does Mustang do this?

question
fullmetal-alchemist-series
How can Colonel Mustang create his flame alchemy differently?


It's his Ignition Claws. As explained in the 2003 Anime Episode "Fullmetal VS
Flame", they create a spark when he snaps his fingers and he uses alchemy to
manipulate the other elements to make explosions or fire. The claws have the
transmutation circle on them, so if it's removed he can't use it, which is
demonstrated during the fight and also later in the 2003 series when he fought
Pride.

Ed on the other hand claps his hands because he's been to the Gate of Truth
and creates a full array with his own body, thus requiring no circles. It is
something only those who have been to the Gate of Truth can do, like Izumi.

While I refer to the 2003 anime, the fundamentals of Mustang's alchemy would
be the same as how alchemy works is the same.

The clapping is only necessary if one does not use a transmutation circle. As
stated by Scar, it is necessary to create a ring using the palms (in order to
create the flow of energy properly). This is the case for Izumi Curtis and
Edward Elric initially, being the only ones to recall their time within the
Gate of Truth. Later (spoilers up to episode 60 or so),

Those using Philosopher's Stones are exempt from this rule for unknown
reasons; it is perhaps such that the stone can provide the necessary flow
without a circle.

You will notice that other alchemists who have transmutation circles need not
clap: Major Armstrong, Basque Grand, and Giolio Comanche if I remember
correctly. Even Al, after drawing a circle, does not clap:

Roy Mustang's flame alchemy is done by the transmutation of air (compressing
it very densely), then creating a spark with his gloves to ignite it.

Edward claps to perform transmutations because he has seen the Gate when he
attempted human transmutation. As a result, this, as explained by Izumi Curtis
(at least in the manga and the Brotherhood anime) means that his body becomes
an array, and so he can perform alchemy without a circle.

Mustang, as explained in the manga and 2003 anime, uses gloves that will
create a spark when he snaps his fingers. Since the transmutation circle
required is on the gloves he wears, he can perform the transmutation without
drawing out the array. There are also other alchemists in the series that
don't clap to perform alchemy: e.g. Armstrong, Kimblee, or Basque Gran (at
least in the manga), so Mustang isn't the only character who does this.

The Ignition Claw theory cannot be true, for during the fight with Lust in
Brotherhood, Roy didn't have his gloves on. Rather, he snapped with his bare
hands while sporting a Transformation Circle on his opisthenar.

What it could be is the constant construction of H2O and deconstruction of H2O
using the oxygen and hydrogen already present in the air. By continuously
reconstructing and deconstructing the hydrogen and oxygen withing the air, you
create combustion within an initial energy source to start it. If you are
interested, please take a look at Oxygen and Hydrogen combustion.

We also note that he has difficulty using his ability during the rain, and it
can be said the humidity within the air may affect his proficiency at the
construction and destruction of H2O; considering that the combustion involves
the CONSTRUCTION of H2O rather than the destruction of it, it would be
considerably harder to get a response in wet environments.

EDIT: Ah. Okay. I haven't finished the series, and I haven't picked up on an
explanation yet. I was Googling around for one but wasn't satisfied, so made
one up.

Mustangs ignition glove is made from a material that produces a spark when
rubbed together

His glove also has the Transmutation circle on it

If I remember correctly or have correct knowledge it has something to do with
breaking down of H2O in the air to make pure forms of hydrogen to ignite a
line of flame and oxygen to keep the flame Alive long enough to reach his
target My theory on It but it may be different

Roy's gloves are made of a special material called ignition cloth, when he
snaps it makes a spark. Then using the transmutation circle on the back of the
glove,he uses alchemy to change oxygen density within the air molecules, then
rapidly expands and contracts then by combusting hydrogen and then using the
spark to ignite it.
