PLAN No. 281. MAKING CLOTHING FIREPROOF

To make clothing fireproof, and thus save hundreds of precious lives, dissolve one pound of ammonium phosphate in one gallon of cold water, and in this soak for five minutes the fabric to be fireproofed. Then dry, and it will not burn. It does not harm the material. It sells for about 25 cents a pound in the drug stores. Make it up and sell it at $1 per gallon. But when the cloth is washed it is no longer fireproof, until treated with this solution again.
