The history of paper is fascinating. Papyrus was the first paper-like writing material in Egypt made from reeds around 8 to 10 thousand years ago. I don't know when rice paper in Japan was invented. Bamboo was used in China. In the European Middle Ages linen rags were pounded into pulp for very high quality paper. With the colonization of America the same was done with cotton. Paper from wood is relatively recent. Also the same pulp used for paper has been mixed with glue and sawdust to make a wood-like composition for at least 200 years.

Great video. Corrugated cardboard already has water soluble adhesive in it (usually corn starch or sodium silicate). If you save the water that you squeeze out , you can use it for your next batch. This will allow the use of less added adhesive.

[@pixelpatter01]

Sodium Silicate or "Water Glass" is used as an agent in paper and cardboard but it is a one time use chemical. After the sodium silicate is exposed to the air it reacts with the small amount of CO2 in the air to form silicon dioxide and sodium carbonate. The silicon dioxide, chemically the same as sand, now binds the paper fibers together.

[@StoneAndersonStudio]

@@pixelpatter01 I believe you- but do you have a source for this information? I was arguing with someone recently about if dried sodium silicate is safe to breathe, as I thought it contained SiO2 (respirable crystalline silica) like you’re saying. Thanks!

[@pixelpatter01]

@@StoneAndersonStudio I learned about sodium silicate from a chemistry set I got for Christmas when I was ten years old. You can search the net for references to it and CO2 curing of sand molds. Using CO2 sources speeds things up but even air will harden a paper wet with the solution overnight because of the .04% CO2. I suppose the silica formed could be a respiratory hazard but then again so could walking on the beach. Just about any type of dust is bad if inhaled.

Shellac is one of the oldest waterproofing coatings in history used on wood. It's plant-based (Toxicodendron vernicifluum) and would be a nice post process for this material. Excellent video!

[@jeffspaulding9834]

I second the shellac suggestion. It's a good waterproofing solution (although it dissolves in alcohol) and it's completely natural. However, if you buy shellac you're almost certainly not getting something from toxicondendron vernicifluum. You're probably getting lac bug secretions. Mix them with alcohol (or buy it premixed in a can) and you've got a relatively durable waterproof finish. There's a million tutorials on the 'net for working with this stuff and it's easy and safe. Lacquer from toxicondendron vernicifluum is not easy or safe (at least until it's cured, after which it's food-safe). It's like painting with poison ivy. It requires a lot of practice to apply properly and almost everyone has a horrible allergic reaction (again, think poison ivy - it's the same chemical) to the uncured stuff. It also takes a long time to apply, as you generally do quite a few thin coats, each of which has to fully cure before you move to the next coat. If you mess it up, you run the risk of giving anyone that touches it a horrible rash. Traditional lacquer isn't seen much outside of Asia - mostly because we have synthetic stuff that is very much not environmentally friendly but is a whole lot easier to work with. The stuff you buy at Lowe's or Home Depot will be synthetic lacquer. Shellac and lacquer are two terms that get very confused, mostly due to their shared history, the way they're written in Sanskrit, and the way "lac" sounds like "lacquer" in English.

[@GryffenHanson]

You are confusing two different kinds of finishes. What you are describing when referring to the plant based qualities of (Toxicodendron vernicifluum) is actually Lacquer. Shellac is a different kind of finish made from the shells of the Lac bug, is not plant-based, and must be dissolved in an alcohol in order to be administered. They both create a polymerized wood finish, but they are not the same, and have different consistencies and properties. Hopefully this is helpful :)

[@ShadowoftheDude]

@@mayurmahale3049 With one coat, no, it would not be fully waterproof, because it will be absorbed into the fibres. However, with multiple coats (allowed to fully dry, which would take 24 hrs at least), or with a sizing underneath (like starch glue, shellac, gellatin), it will become fully waterproof. An alternative is to coat it with a natural resin varnish after the oil. Yes, a phenolic resin, or any other synthetic coating, would render it waterproof immediately. But I recommended drying oils because in the video they explicitly said they wanted an environmentally friendly finish.

Again, lots of ways to to make it water resistant enough to be useful in daily life without wrapping it in a plastic seal.

There was a resin company they partnered with to create these bio-resins for fishing net floats as well as swimming boards. The core would be mycelium and the outside coated with resin.

[@paintedwings74]

Length of fibers is an ideal thing for cohesion, but I'd think that the compression would be difficult to maintain, as the original fibers would have something like "memory" and your end product would start fraying just a bit at the edges along the original edges of component cardboard? What I have had good luck with when making paper logs for burning is soaking our paper for a while until it's thoroughly soggy. Then the blender step need not take very long, which I would guess leaves far more long fibers in place compared with having to shred it from dry, still-coherent cardboard /paper.

@@alexmcfly31415 Just my two cents but anything can be flammable. You could use a file/sand and get small powder particles from the cardboard-molded part and put a flame to it, and it (the thin/small particles) will quickly catch fire. Things are just less flammable in general when the object has 1. less surface area 2. is much denser 3. more volume which gives greater heat capacity and a better means to transfer heat away from the hot surface. Only the surface (and not the inside) has a means to catch on fire because fire requires oxygen as fuel, its very difficult to get a block to maintain a fire, it just takes more time to bring up the heat of the object to keep the steady flame. Its mostly about the shape, hence why powdered metal is highly combustible and must be stored safely. Speaking of powdered metal, that's how 3D printing works for metal printing, as metal powder can quickly reach its flash point and melt. Powder metal companies' goal is to make the most spherical powder.

When i worked in a paper making studio all of our raw material got presoaked, this helped us control the ratio of cellulose to water that we needed to pull sheets of various weights. Might require a bit more putzing to figure out what ratio is right for any given mold, so I'd suggest establishing an idea density for a finished piece and try and work backwards from there to calibrate that ratio. As for using a hydraulic press, i'd say only use it if you want to scale up. In the studio I worked in we used hydraulic presses only when we had at least 50-100 sheets pulled (and we were a small shop). If you're interested in exploring water proofing maybe look into wax. Again it will take some experimenting because most fibrous mediums being wax coated are flat. If this kind of production were to be scaled you'd also need to invest in a good dehumidifier.

I would use PETG molds, because for better or worse, nothing likes to stick to it. Then maybe mix in a ratio of Titebond III just before pouring it. When done properly, Titebond III can glue wooden surfaces stronger than the grain of the wood itself. It’s also great with paper.

I agree on the too dense. The sound waves get dissipated by the surface shapes but also captured/absorbed by the lose lattice shape of the the foam itself. I won’t say that this wouldn’t work but may be need to tweak the shape to create “bottomless pits” on the paper to make sound waves fall in from the surface and have a hard time to bounce back intact.

What if you used acetone instead of water and added styrofoam as the binder to recycle syrofoam. You would have to use an undisolvable type of plastic or metal as the mold but it would help and reuse styrofoam and it would be more resistant to water

[@ethanm9191]

Someone needs to do this

[@rileywebb4178]

The acetone would also interfere with the hydrogen bonds between the fibers after water is removed, which would mean the strength would be reduced. The acetone might not cause this, but for example butanol does.

[@rileywebb4178]

Regardless, the wet strength would not be increased unless something like a wet strength agent (the specific one would depend on the pH of the pulp) was added to the pulp. Sizing which would slow the penetration of water may also help, but would depend on the pH as well and would also require specific chemicals.

Safety Tip: Always wash the egg cartons, before reuse as salmonella lives on the egg's shell. Small amounts can be present that won't make you sick eating the inside of the egg and boiling eggs usually kills these smaller amounts. A quick wash with hot water or just a little soap will kill any lingering salmonella, especially important if you use that blender for foods again in the future.

[@joncue0304]

If you want to make it easier to take out of the mold, you can add a draft angle to the mold, just like injection molding.

[@GnuReligion]

Yes, the rules for injection molding will apply. I purpose planters, like Peat Pots, as a practical product.

this is not possible because of the part that presses paper inside the mold. in process some paper will be trapped between walls of those two parts.

Hi, probably too many comments for you to read this one.

[@ared0hel]

@@XYZAidan I would recommend wool roving. Roving has all it's fibers arranged in one direction( for spinning into yarn) and can easily be pulled apart into separate fibers for mixing into the slurry for random fibers, or can placed in the mold as Conny suggested. *stares at saw dust embedded in mittens* It also attaches to wood fibers really well.

@@XYZAidan A lot of people have suggested hemp but if you can get it flax fiber (the stuff that is spun into linen for fancy suits) is a VERY long fiber. Long strand raw cotton also has some interesting properties though cotton isn't the most environmentally friendly thing. There is a kind of almost indestructible paper made from bamboo pulp. Nice yarns as well. All long fiber and extra strong.

[@richardattenborough5360]

The paper can cause mold and water issues for the seed, which is why they use the current specially developed system. There is little room for error when it's difficult to go back for more seeds. This method s actually the most basic one for that kind of application and I'd be pretty shocked if they'd never tried it in a very preliminary stage. It would also be quite a problem controlling the water inside and keeping it safely contained. The smallest amount of water and particulate can be dangerous to the systems of the spacecraft.

Look at how carbon fiber is molded; they use vacuum bags to infuse the resin and remove air pockets, as well as ensuring a good cast from the mold. I think if you want to use the same method, you'd need to blend the dry paper with one of the two parts before mixing them like this. It wouldn't be neatly enough to remove the water, as 1 atmosphere of pressure is only 101 kPa, and a c clamp (not the same as used in the video, but a similar screw mechanism) can produce up to 2000 kPa.
