It's wood filled with a polymer that makes it translucent. "Invisible wood" is just a name for it. The articles don't really address whether wood treated this way is any more or less flammable.

Keep it up and I might hit you with the Wood of Doom. Now if you would please hand me the Mod of the DoE Wod Dom.
I got hit by the Wood of Doom a long time ago - by my wife. Surprisingly, not actually made of wood. My Hat of D02 know no limit. What?
Just what i need for my kitchen, will a invisible open wooden kitchen door leave a invisible bruise when i bang into it. lol
