Cellulose sponge material is flammable although combustibility rates can vary with impregnated fluids. Thermographic analysis with cellulose shows that sponge starts to burn away at more than 300 °C.
Are sponges toxic?
Sponges also produce their own toxins through normal metabolism, or in collaboration with the many microbes that live inside them. Whatever the source of these toxic chemicals, many have been found to be highly toxic to other life forms.
