Hey guys as a heads up. In the lab if we make silicone we always degas the mixture before pouring. To degas just put the silicone after mixing into a closed container and pull vacuum. I think even a cheap aspirator will pull enough vacuum to work. Pull until the bubbles stop than you're good to go.

Both look promising. Google degassing silicone for more it's a common technique in soft litho.
Edit: For a chamber just get a plastic dessicator. They aren't that expensive : https://www.amazon.com/United-Scientific-55204-Polypropylene-Polycarbonate/dp/B00ES3GPMM

Remember keep the vacuum so that it slowly degasses you do not want it to bubble over and all into your chamber.
Vac systems are getting shockingly Cheap. Vac Purge Kit
Depends on how much vacuum you want. You can suck a significant amount of air out of a bottle with your mouth by sealing your lips over the mouth.
With a small handheld vacuum pump you can create even more.
With a home food sealing machine, you can create about the best vacuum you're going to get without a much more expensive pump. Interestingly enough, the "vacuum" these machines produce is very near the atmospheric pressure on Mars.
Vacuum is dangerous if you put anything living into it, or if you try to draw a vacuum on some container that doesn't have the structural integrity to hold it, it will implode.
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:
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!
If there is running water these pull a strong vacuum, and cost nearly nothing.

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.
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!
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

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.

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.
Here's the pressure pots I was referring too. Various ones are designed for heat or pressure or vacuum

I wouldn’t say there’s a lot of debate over decarbing. It’s pretty well agreed upon that if you’re going to put your extract in a cart then you need to decarb so that you 1. have an extract that’s fluid enough to wick on your cart and 2. prevent your extract from crystallizing in the cart.
If you wanna take some of the guess work out of decarbing, don’t do it before your extraction. Once you have your extract you can decarb it at 200f and instead of using a timer you can watch it bubble. As the extract decarb a you can visually see the carbon dioxide bubbling out. So once almost all of the bubbling is gone, your extract is finished decarbing and you should have a less dark concentrate.
Dry ice is what you want. Not liquid nitrogen. Nitrogen will freeze your got damn hand off. So will dry ice, but not if you’re wearing some thick gloves haha it’s like 2 dollars a pound where I live and for something small scale you should use too much.
Vacuum filtration is a MUST. You don’t necessarily need an expensive vacuum pump for this, instead you can get away with a faucet aspirator . They are pretty cheap and let you get enough of a vacuum to filter. You can get away without vacuum filtering on high micron filters without a lot of sediment, but if you want to do low micron like you mentioned or get into carbon filtering gravity filtration can take hours.
Those liquifiers can contain some real garbage in them. Pg, Vg, PEG, mct oil (mineral oil based on some independent testing of True Terpenes supposed “100% natural terpenes blend”) and who knows what else because MOST OF THEM WON’T TELL YOU. It’s a proprietary blend. If you can afford it get a blend of terpenes. Floraplex actually offers msds sheets for their products, so you know what’s in it. Mass terpenes does not do this, but they get a lot of support from the community along with Mr. Extractor. Mass terpenes and floraplex are quite affordable too!
how i got started
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:

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..?
Hydrion Scientific 5 Gallon Vacuum Degassing Chamber https://www.amazon.com/dp/B072MM97P3/ref=cm_sw_r_cp_apa_ihYwzbFNEWCG2
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?
you probably need more material and a vacuum chamber.https://www.amazon.com/dp/B00W8ZU5FK/?coliid=IKPZI52V796YI&colid=3HUBTLT676WDO&psc=1&ref_=lv_ov_lig_dp_it
this is one i have on my list for my dice making project for later. You want to put your unpored resin into the chamber for 20 minutes, then put in your dice for 30 minutes. Always put something under your molds. you can leave the dice to cure for 20 some hours in the chamber turned off. If you want my dice amazon list i'll gladly hand it over.

This guy gives lots of good tips.
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.

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.
I use this vacuum chamber

And I use this pressure pot
California Air Tools 365B 5-Gallon Pressure Pot https://www.amazon.com/dp/B008FQEC6Y/ref=cm_sw_r_cp_apip_GIVbOaA1tAb1O
I also had to get some fittings and modifications for the pressure pot but I can't recall exactly what. I like quick disconnect hoses and fittings and the pressure pot didn't come with anything.
To be honest you don't really need a vacuum chamber, depending on the application. Smooth-on Smooth Cast 325, 326, or 327 are all low viscosity and don't seem to bubble as much. You can get by with just a pressure pot and an air compressor.
For the love of all that is holy, though: PLEASE WEAR GOGGLES. I can't stress it enough. Resin in your eye will ruin your vision. Also, when dealing with pressure you're always running the risk of a breach and even dust at 50PSI can ruin your vision.
Surprisingly not really unlike Oregon. Where we have hundreds of farms, and ridiculously cheap flower, but so little oversight that they grew so much weed that there’s like literally a million pounds just sitting there waiting to either be sold, turned into oil, or go bad.
I’ve always wanted to come to Israel but my health hasn’t allowed for it. I’m kind of out of town Modern Orthodox. My sister managed to get out of here though. She went to seminary at Neve Yerushalayim when she was 17, moved to Manhattan, and has only come back a few times in the 6 years since. Oregon is too treif for her now lol.
I do know some people there who have made small amounts of their own though. It’s not something I recommend doing if you live in a city, but something that I imagine you could get away with easily by driving off into the desert or something. And everything necessary other than the herb, including the butane is available on Amazon. This is a good starting point.
Ablaze Stainless Steel Open End Tube Kit 45 Gram (No Tripod) https://www.amazon.com/dp/B01MS0BTGG/ref=cm_sw_r_cp_api_i_kv2VCb729DWJS
With one of those, all you’d need is butane, which is also available on Amazon.
If you want to take your product a step further, you can add a quality vacuum purger that comes with a pump for right around $150 now. All in all very little expense required to make something very valuable in places where it’s hard to find.

Yes please be safe and use a Purge to be sure extracts are clean.
Good vacuum, fast, cheap. Pick any two.
To meet your criteria this one linked below is under $50, will pull a better vacuum than most mechanical pumps, but very slow by comparison. Also wastes a lot of water. Probably not suitable for the task.
Lowest priced practical pumps will be Harbor Freight or local equivalent starting at $100 and more like $250 for anything over 4 CFM. I get them over Craigslist for sub-$100 (7CFM in that case). The decision on CFM is a factor of vacuum chamber volume and silicone working time.
Good luck with that search!
Aspirator vacuum pump
Oils are nonpolar, so you would probably get the best extraction with a nonpolar solvent (i.e. not water). The easiest starting point would be to use Everclear (95% ethanol) to extract from some chopped up hops, filter it, then slowly evaporate the alcohol.
You also might try some other high fat food products (milk, plant oils, butter, meat fat) to do the extraction, but it will be impossible to separate your solvent from the hop oil.
It probably wouldn't hurt you to read that info about THC (or even caffeine) extraction. A lot of the same principles will apply.
If you want to go further, look into converting your kitchen sink to a water aspirator pump or making a CO2 extractor yourself.
Lastly, I have no idea if this would work, but maybe you could make a "hop espresso/tea" with a moka pot? Also try with everclear.

Just make sure your hose water isn't going down the drain - because you don't want your butane down there :P
