Wood makes for better walls than windows — most of the time.

Researchers from the University of Maryland devised a way to strip the colors and and chemicals from a block of wood to leave behind a clear, transparent material that’s stronger and more insulating than glass, and biodegrades better than plastic.
Only Two Steps Needed

The process of turning wood into windows is actually a pretty simple process. First, the researchers put blocks of wood in a boiling bath filled with water, sodium hydroxide and other chemicals for about two hours. This caused a polymer known as lignin to leach out of the cell walls in the wood. Lignin is one of the most common compounds in the plant world, and its chief function is making plant cells more rigid. Crucially for the researchers, lignin is also what gives wood its color — with the compound gone the wood turned white.

Then, the researchers soaked the wood with an epoxy, which both strengthened the wood and turned the wood clear. The secret lies in the natural architecture of the wood, combined with the refractive qualities of the epoxy. Even though its color was gone, the underlying structures in the wood remained the same, including the tiny channels that trees use to transport nutrients. When filled with the epoxy, these channels turned into conduits for light, focusing it and allowing it to pass through. The end product looks more like a piece of plastic than something that once stood in a forest. They published their work in the journal Advanced Materials.
Wood Beats Glass

The transparent wood is stronger than glass and won’t shatter on impact. But wooden windows have a ways to go before they start appearing in homes.

Currently, the researchers can only treat wood chunks that are up to about four inches to a side. In addition, they are currently limited to about a centimeter in thickness, although they have made clear wood that is as thin as a sheet of paper as well. A separate team of Swedish researchers also recently managed to create transparent wood with a similar method, although their wood was not as thick, and did not let as much light through.

As of right now, the University of Maryland researchers say that their wood achieves a 90 percent transmittance rate for light.

What's special about transparent aluminum?

Also You mean transparent aluminum like this:



Aluminium oxynitride or AlON is a ceramic composed of aluminium, oxygen and nitrogen. It is marketed under the name ALON by Surmet Corporation.[3] AlON is optically transparent (≥80%) in the near-ultraviolet, visible and midwave-infrared regions of the electromagnetic spectrum. It is 4 times harder than fused silica glass, 85% as hard as sapphire, and nearly 15% harder than magnesium aluminate spinel. Since it has a cubic spinel structure, it can be fabricated to transparent windows, plates, domes, rods, tubes and other forms using conventional ceramic powder processing techniques. AlON is the hardest polycrystalline transparent ceramic available commercially.[2] Combination of optical and mechanical properties makes this material a leading candidate for lightweight high-performance transparent armor applications such as bulletproof and blast-resistant windows and for many military infrared optics. AlON-based armor has been shown to stop multiple armor-piercing projectiles of up to 50 cal.[4] It is commercially available in sizes as big as 18x35-inch monolithic windows.[5]

It would be great for painting artwork on where the front of the painting is against the wood. Kind of like giant anime cels.

Does this work on all wood? ( ͡° ͜ʖ ͡°)

You mean that documentary about how that guy got the formula for transparent aluminium?

for all we know he would've invented it himself eventually

well the one you posted is a ceramic, the one I was referencing was actual metal
