step 1: remove most of the wood
step 2 replace the 90% of structural material that you've dissolved with a marine epoxy that goes transparent in UV
step 3: put it in the sun
congratulations, you now have a transparent piece of epoxy. In the future you may even make windows out of it if people ever start preferring plastic windows

I see your point
But are the "most" and "90%" based on actual data? The properties of a cellular structure impregnated with resin could be very different to just resin.

once you remove all the lignin, and fair whack of the celluose and hemicelluse, can you still call it wood?
if you got a corpse, let the maggots eat all the flesh and put the skeleton in a chemical bleach it until was all degraded, then covered that skeleton with epoxy, would you say "hey, we've made a transparent human"? I suspect they're using the term because it sounds more green than what it is
you can add a lot of thing to epoxy to change its properties, no doubt. Fiberglass springs to mind. I'm sure a lattice of degraded cellulose has some effect. But they compared its thermal properties to glass. Id like to see how it performs against similar epoxy polymer sheets to see if it's worth the fuss

I read the article and you have fundamentally misunderstood what was written in it.
1: Painting 1mm strips of wood with h2o2 is not 'removing most of the wood' or dissolving it. Painting wood with h2o2 is an additive process.
2: Painting white stained wood with marine epoxy is not replacing dissolved structure, it's filling in natural depressions that you find in wood.
3: The wood, h2o2 and marine epoxy combine, you delightfully confident man.

they said it removes all the lignin, so it's not an "additive process", dingus
it depolymerises the lignin, breaking down the long plant polymers and releasing oxygen and a bunch of short chain ketones that would evaporate, which is why they stand them up and hopefully don't breathe the fumes.
(edit) just had a look at the lab data ((https://www.mdpi.com/2073-4360/11/5/776/pdf). The hydrogen peroxide actually removes a fair bit of the cellulose and hemicellulose along with the lignin. It states lignin removal is "from 29% of weight down to 2.9%". You'd apologise for your unwarranted superciliousness if you had the least bit of class about you, brb. pretty much everything you stated is wrong

"replace the 90% of structural material that you've dissolved"
how much of the wood is removed?

look up the percentages yourself if you're fascinated in knowing the answer
i feel like Ive defended my comic reply enough to would-be pedants. Sometimes I wonder what some are doing on a comedy website

is that that what you claim after being wrong? how convenient
is your whole account one long troll dedicated to dimwitted argument? I'd say well played sir, for such a sustained performance
