Interesting idea! I went on a hunt and this is the coolest thing I've found:
It's done with a process called plastination:
> The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most properties of the original sample.
They're been doing this since 1970s so I figure there's probably a guide online. Next logical step was a search for "DIY plastination":
I do not have any evidence that the same procedure would work on mushroom flesh, other than the flickr link above.
EDIT:
Per the plastination patent by Gunther von Hagens:
>EXAMPLE 3
>A globular cactus having a diameter of approximately 15 cm was partly hollowed out from its root end by means of a curette, and it was then immersed sequentially for three hours each in 50% aqueous acetone, pure acetone, and dichloromethane. Thereafter it was immersed in a solution of a commercial epoxy resin prepolymer stable at low temperature, but curing at elevated temperature. The vat holding the prepolymer and the immersed cactus was stored in a vacuum at 10° C. for eight hours, whereby all volatile solvent was extracted. When drained of excess prepolymer and held in an oven at 40° C. for six hours, the cactus hardened, but otherwise retained its original appearance and color.
Just curious how much a DIY setup would cost so I made a shopping list:
I bought a small vacuum chamber from Amazon.

Also got the vacuum pump they recommend in the "often bought together"; you don't need the adapter that is recommended there though. I use it to degas my silicone for molds and just to pull any big bubbles once I pour resin so I know the mold is full (do not degas resin, it's bad news bears).
And I got the 5gal pressure pot from Harbor Freight which you see recommended a lot. Also got a small, oil-free airbrush compressor there that auto stops at 58psi as the recommended Max for the pot is 60. With it, make sure you get shut off valves and an adapter that will fit the compressor hose. An employee can help! If you don't have a harbor freight locally, I recommend calling their services department instead of trying to navigate their website. Make sure to get good thread sealant to stop air leaks at all the junctions; I used Loctite red and coated both the female and male threads before tightening. I also recommend a couple of small c clamps as the lid doesn't always seal well and you don't know until you're up to 40/50 psi, so they work great to put a little extra pressure on the seal wherever it's letting air out (you'll hear it). Don't over tighten the c clamps as you don't want to warp the lid seal.
PS. Not an expert, just what I've used/learned over the past month of messing with these in my free time.
Hello, r/CannabisExtracts! Visitor from r/microgrowery here. I'm wondering if you experts can help me dial in my blasting technique. Here's what I did:
How did I do? I haven't tried it yet, but it smells pretty strongly of chlorophyll. I'm afraid that this will be suitable for making edibles, but not so good for dabbing. Please give me your constructive criticism. Thanks, fam!
Purging flammable butane out of your extracts in your gas stove is a great way to blow up your house.
Get one of these and a pump.

Vacuum chamber and pump ~ 150
Pressure pot ~ 104
Air compressor ~90
I used these or similar in the past to get started. Most people don't need a 600+ 10g pressure chamber or a giant air compressor.
My 2 cents.

Autoclave vs. disposable alternatives: like plastic covering?
This is really intereating. I have never made my own media but use several at work. I'd like to know what u are growing on which media?
Often, when I don't recover an organism I wonder if my media is the limiting factor.
The one I've been using works great. This one is marketed towards the marijuana industry for making concentrates, but its no different than any other vacuum chamber. The only difference between mine that that one is that I bought that vac chamber alone, and a Robinair 5cfm Pump separately. That first link wasn't an option when I bought it.
Here's the pressure pots I was referring too. Various ones are designed for heat or pressure or vacuum

That pot will hold a lot of wood, but you also need a couple gallons of Catus Juice to fill it. Grab a cheap toaster oven from Salvation Army to cure.
Listen to /u/Glock19mos. I don't typically dye (I purchase mine dyed) and his pictures speak volumes about his capabilities with the process.

the vacuum pumpdoes work you just have to get it stable enough so it does take longer to put a vac on it. The hand pump is more about the work you have to put into getting a good vac. Alot of pumping. If it was a 3 gallon chamber it'd be ridiculous. I got the 1.5 quart chamber just for space saving reasons initially. It takes a bit of pumping, but I can get it to a vac and keep it at 27-28 depending on how im feelin'. It works great as small portable gear.
Just a vacuum. My chamber is aluminum and is a bit more expensive setup than a food dehydrator, but I bet a small chamber could be printed, which would bring the cost down. Another substantial cost is the pump itself. It MIGHT be possible to do this with a hand operated vacuum pump if most of the void space could be elliminated within the chamber, maybe with rice or a desiccant. Basically you want most of the air out when you start so you don't have to pump much.
In summary, with a printed vacuum chamber (would need to be well engineered to prevent implosion which would not be fun) and a hand pump this could actually be quite a bit cheaper than alternative methods. It's definitely safer for your spool and oven, lol!
Oh, and an interesting thing about the desiccant: It gets quite warm when it's adsorbing moisture, but not nearly warm enough to melt any 3d printer filament that I'm aware of. This warmth should make the filament dry out even faster. It also will keep the pressure in the chamber lower since it will adsorb water vapor surprisingly quickly.
Now if I can get an analytical balance we'll be in business!
A vac chamber with a heat mat is cheaper.

Other supplies you'll need: vinyl gloves, cardboard and hot glue gun to make the mold box, paint mixing sticks, graduated measuring cups, disposable coffee cups, silicone or mica pigments, release agent (smooth on universal release agent), and a whatever you want as a model
Edit: if you have any other questions feel free to pm me
If it's mostly for personal use and you might upgrade in the future to something bigger like a full oven vac ($1000-$3000+). Then it might be worth considering something cheaper
https://www.amazon.com/ABLAZE-Gallon-Stainless-Degassing-Chamber/dp/B071KZXVRR/
Could then save for a bigger system and still get at least a few good runs out of something cheaper. BVV are overpriced in my opinion
how i got started
I use a heat pad made for chambers. It keeps the heat accurate over days. My last batch took 3 days in my vac at 94* to become 100% stable.

I am looking at something like this maybe..?

In line to the pump would be a stainless steel coil to collect condensation and then a filter to keep vapors out of the pump.
Would this work?
Long and then short reply lol, I’ll get back at you further when I’m less busy, but here is what I’m talking about for that screen. I def had better luck when I switched from trim/popcorn nugs to “premo” nugs too so hopefully that helps your situation.

Also, if you don’t have one this may help with heating your vac chamber long term, I love mine:

It will likely all need stabilization; not much is pulled up anymore that's gem-quality hardness. The hardness relates to the dryness of the mineral; the stuff closest to the surface with the most exposure to air will, over millennia dry and become hard. But that's the easy stuff to mine, so there's not much left.
You can stabilize yourself; it's not difficult but does require a small vacuum system like this, along with a stabilizing agent like Opticon. Depending on the rough, you'd likely stabilize twice - the first time for cutting slabs, and then each cut slab as well. I use a 5-gallon vacuum chamber and can easily get a dozen slabs in it.
Worrd thanks for the info bro, now I'm considering getting a chamber too just to be safe. What you think bout this?

I know it ain’t cheap, but why not use a vacuum chamber?

You would effectively increase the pressure in your cans without changing temperature and messing with seal compound.
FWIW, this is a method used for other containers.
I haven’t bought one yet, but I’ve been doing some research into it. Stay away from acrylic lids. Some of the materials you use can damage the plastic. I’m leaning towards this one.
Anybody knows where to buy a small vacuum chamber? Amazon JP offers me expensive industrial ones, and I just need a tiny one for my hobby cast thingies
Starting us off, one of the first piece of equipment I need to get is a pressure pot. From what I've read they are useful for mold making as well as dice.

I'm currently looking at the Ablaze 1 gallon pot, currently $68 on Amazon. Is one gallon enough to make dice? Harbor Freight has a larger one but Costa more.
