New Scorch Test - Flameproof Paper

This is a test on the paper that I bought from digital print and is specifically made for lampshades. This flame proof paper ahd the same effect as the fire retardant sprayed paper. I held a lighter to it and at first it took a while to discolour, then turned fully black, but never set on fire, the paper started to singe and glow with heat but just turned to ash once scorched, no flames.
