I want to know the answer to the following question:
Rayon comes from what plant product?
All the background I'm provided with is that "Charcoal, a pure form of carbon made by pyrolysis of wood, has a long history as a metal-smelting fuel, as a filter material and adsorbent and as an artist's material and is one of the three ingredients of gunpowder.". Is that enough to answer the question?
Answer: no
