Can you melt wood?

BBC Earth (Asia) - - Q&a -

No. Wood is mostly cel­lu­lose, lignin and wa­ter. If you heat wood, the wa­ter boils away first and then the lignin and cel­lu­lose (both long-chain or­ganic mol­e­cules) will re­act with oxy­gen and burn. Even in a vac­uum, these molec­u­lar chains are too long and tan­gled to wig­gle free into the liq­uid phase be­fore they reach tem­per­a­tures high enough to break their bonds. In­stead they break down into smaller sub­stances, like meth­ane and or­ganic com­pounds con­tain­ing car­bon and hy­dro­gen. RM
