IIRC it's not replacing the lignin -- the lignin are the tubes that give wood rigidity. This process removes what is inside the lignin with resin.

- veddox 3y agoThe tubes are called xylem and phloem. Lignin is one biopolymer that is used in their construction, but it's not the only one (cellulose is even more important) - and you shouldn't confuse the building material with the structure. Also, the article specifically says that these processes will usually remove the lignin to make the result transparent.
