are there any substances that you know that are fire resistant & can be used for paper?

Answer 1

Asbestos?


Wait, did you want non-toxic?

Answer 2

Whether the paper be plain, written, printed on, or even marbled, stained, or painted for hangings, dip it in a strong solution of alum-water and then thoroughly dry it. In this state it will be fireproof. This will be readily known by holding a slip thus prepared over a candle. Some paper requires to imbibe more of the solution than by a single immersion, in which case the dipping and drying must be repeated until it becomes fully saturated. Neither the color nor quality of the paper will be in the least affected by this process, but, on the contrary, will be improved.

Go here to see Flamex Fire Retardant Spray which you can spray on paper and other things also. A non-toxic, spray applied fire retardant for cotton, wool, cardboard, straw, paper and interior unfinished woods:
