[Material] Silk [Time to burst into flame] 7.6sec
Wool and silk (protein fibers) shrink from the flame, are hard to ignite, smell like burning meat or flesh, sputter as they burn and leave a crisp, foamy crushable residue. Although these fibers have natural flame retardance because they are difficult to ignite and burn slowly, fabrics of these fibers often burn easily because of an open fabric weave or knit and dyes or finishes present.
