FIRE DENYING LIQUID.
Denver Mans Discovery to Make Wood
Fireproof.

Fireproof.
Spurred to the labor of discovering
liquid applications Of which would rem
der canvas and wood imperyious to
fire by the disaster in the Iroquois
theater in Chicago, Professor Carl E.
Kruger of Denver announces that he
Is now able to formulate colorless,
odorless fluid the presence OF which
cannot be detected, at the slight en-
pense of 10 cents Il gallon, which rem
ders combusubles with which 1t comes
In contact absolutely fireproof. says
the Columbus Dispatch.
Professor Kruger Is German, SIX
ty years old, and Il photographer. He
has been in that business since 1896,
when he began polishing daguerreo-
type plates for his father. at that
time it was necessary for the photog
rapher to manufacture his own sup
plies, and Il knowledge Of chemistry
was essential. Professor krueger stud
led chemistry under DR.. Nogel of Der
lin and ut that time began expert
menting in the photography OF colors.
He says he has succeeded In catching
light red, brown and blue with the
camera, but will not attempt to make
pictures for the public until he is able
to take deep red and yellow also.
Professor krueger. to test the quail
ties of his fire defying liquid, per-
forms number of experiments. A
single Is dipped into the fluid, al
lowed to dry and then dipped In kero-
sene which is ignited. The oil burns
and the single IS charred, but Its
strength and solidity are unaffected.
Canvas prepared with the fluid Is
soaked in kerosene The oil burns
out and the canvas is only blackened
except where it has been heated to a
white heat and tlamelessly turned to
ashes. The quality Of the canvas is
destroyed by such test as kerosene,
although 1t does not become ignited.
A small stick Of pine, heavy with
pitch, after being dipped in the liquid.
was placed across faring gas burner.
The pitch was boiled out Of the wood
and burned. the iron Of the heater
grew red, but the little pine stick only
blackened aud came out of the ordeal
as solid and hard as ever.
A soft pine box was sprayed with
the liquid and then stuffed with papers
drenched In kerosene. The flames shot
up through crack at the top, curled
around the sides and seemed to be
burning the box as paper, but when
the fire had died down the box was
only blackened, otherwise intact.
Professor Kruger IS employed at an
Arapahoe street studio. He has been
in Denver off and on for six years.
Speaking Of his discovery. he said:
There need be no more fires on the
stage. where women and little chill
dren will be burned up. In fact, there
need be no fires any place. Roofs can
be sprayed with this fluid and then q
bonfire built on them. Box cars can
be protected and lumber yards made
fireproof.
"a silk dress can be dipped in this
liquid and it would never be detected
and will not burn. l have found that
it will not wash out, but long boiling
will take out the chemical.
"In the future houses can be sprayed
with this and then painted. The paint
will protect the fluid from the rain
and weather and render the house
freproof. feel very proud Of my dis
covery, and l have tested it as severe
~ could. have known for a long
time how to manufacture fluid that
would repel file. but left stain when
applied.
81 have applied to Washington for q
patent, and if can get any money
out Of it l am going to take up photo
graphing in colors. 1t costs money
to experiment. especially in trying to
take pictures in their original color.
because they are not treated like the
other kinds Of pictures"
