JUDGING
FIREWOOD
MOISTURE
CONTENT
You
can
find
out
if
some
firewood
is
dry
enough
to
burn
by
using
these
guidelines:
•
cracks
form
at
the
ends
of
logs
as
they
dry
•
as
it
dries
in
the
sun,
the
wood
turns
from
white
or
cream
colored
to
grey
or
yellow,
•
bang
two
pieces
of
wood
together;
seasoned
wood
sounds
hollow
and
wet
wood
sounds
dull,
•
dry
wood
is
much
lighter
in
weight
than
wet
wood,
•
split
a
piece,
and
if
the
fresh
face
feels
warm
and
dry
it
is
dry
enough
to
burn;
if
it
feels
damp,
it
is
too
wet,
•
burn
a
piece;
wet
wood
hisses
and
sizzles
in
the
fire
and
dry
wood
does
not.
You
could
buy
a
wood
moisture
meter
to
test
your
firewood.

MANUFACTURED
LOGS
Do
not
burn
manufactured
logs
made
of
wax
impregnated
sawdust
or
logs
with
any
chemical
additives.
Manufactured
logs
made
of
100%
compressed
sawdust
can
be
burned,
but
use
caution
in
the
number
of
these
logs
burned
at
one
time.
Start
with
one
manufactured
log
and
see
how
the
insert
reacts.
Never
use
more
than
two
manufactured
logs.
