Tek Pressing Rosin from Nepalese & Moroccan Hash

[Mr. Gweilo 420]

I was wondering if anyone has tried this or can offer any tips. I have been thinking about this project for a while and I put it into action a few days ago. I have been doing occasional micro presses with a hair straightener with buds for a while. I have had moderate success but bud is too expensive here to press a lot. Hash is cheap but trickier to get. This is my first time pressing hash.

I finally went to the shadiest part of town and made a new contact. So far I am pleased with what I got. I get Flower from local triads. They are generally cool and businesslike. I like that. Hashes come from Indians and West Africans. The prices are cheap but I pretend they are not lol. I encourage them to raise their price in hope of getting the best. It is still cheap.

Im not keen on these products as is but feel I can clean them up and dab them. I started on the Nepalese. It works well but I have learnt filters will be the key to turning this into full melt rosin. Here is the best so far:

So I think I need to find filters. 20 micron or 36 sound good? Would you dab what you see in the pic or do you think its disgusting?

Any other tips? Thanks.

my 1st experience with hashish was nepalese temple balls...
fond memories, would never have thought of pressing it.

Well this might become one of those threads where one guy talks to himself but such is life

I have been trying to research this topic further online but it is hard to find useful information. I went ahead and ordered some 25 micron filters from an Aliexpress vendor;

I think the filters are absolutely the key. I squished some more Nepalese today and it was my best yet. The hash is soft and does not require much pressure. I have been starting gently and then adding more pressure over about 30 seconds. It makes a sizzling sound for quite a while. I have not weighed my results but I am getting huge yields. Im more concerned with quality though. It tastes nice too and the taste of the og hash is not nice imo. I notice longer pressing produces a terpier waxy rosin and shorter, harder press a more shatterlike rosin.

Im using a few various makeshift filters at the moment. Coffee filters are not working. The rosin is absorbed by the coffee filter and does not pass through to the parchment paper. The finer the filter the better the result!

What temperature are you pressing at?

With coffee filters the problem I had was blowouts. It only worked with very pure hash pressed very slowly.

I have pressed Moroccan. The hash quality was mediocre, the rosin slightly better. The colour was always brown to black.

Curious to see more of your result.

I've used 37 micron stainless steel mesh in the past with a small amounts of soft hash

Coffee filters work too, but you have to go really slowly and use much lower temps than flower.
[edit] this was pressed between some straighteners & a clamp using paper coffee filters and some parchment:

0.67g from squashing approximately 1.56g of hash, so about a 42% return

Im pressing at about 170 at the moment. Found today time required for pressing to be more like 20 seconds.

Sorry mate I cant access your pics. Im using some mesh appropriated from something else temporarily. I got good results in terms of filtering today. Almost no residue left after dabbing. However, I found longer presses of about 30s producing that kind of concentrate that is very hard to completely collect. Tomorrow, I hope to combine improved filtering with a shorter press. Hope to get something clean and more shatter like. Im on holidays by the way☺

Edit: Sorry I was also wondering about the term blowout? Does blowout describe unwanted materials escaping the filter and ending up on the parchment paper? TIA

I press a good bit of hash currently using some pressclub 37 micron filters at 170 degrees on my 3x7 dabpress plates which is actually closer to 160. I begin my press slow enough that the hash gets up to temp and the goo can turn to liquid before I start to apply any actual pressure. Otherwise you can break a hole in the filter and you get a hash geyser (blowout). This weighted out to 6.5 grams. I used it all in one batch of brownies. They are INSANE.

 

[Mr. Gweilo 420]

@elmomuzz that looks great! Did you use a press? Im guessing that was originally some nice American hash to begin with?

 

[elmomuzz]

Yes I used a 3x7 dabpress. It started as trim grade hash. I yield around 75%.

 

[Haze Mister]

I have tried this with Moroccan stuff. It tasted like crap and the micron bags often split. It wasn't worth the hassle IMO.

 

[BiPolarBear]

This looks very tasty.

Pressing 'solids' is another artform

A lot depends on your preparation. If packed to full bags will rip apart. If pressed too soon bags will rip. If pressed too hot, shit will stink and taste awfull...

But then comes the moment it al falls into place and many 'brooken' bags lead to a tek one can repeat.

Go low and go slow. Go really low, and really slow....

Another tip might be... Bag it up in a 90 or 120 micron bag and then in 25micron. This alone should help you to avoid blow-outs...

Edit: that last picture, the rosin is not levetating no idea why it got turned upside down...

Exactly what I was doing lately @tepictoton ! Where I live hasch is very cheap, one gram cost rather the same than one gram weed, even lower if you get good relations... there some dirty adultered haschs but there is some very good ones too... So if you can get some good quality hasch rosin might be very cheap (around 15€ to get a gram of rosin from 3 grams of hasch). And yes I agree with you at low temp the result might be amazing and very powerfull!

I have been double filtering my hash as was mentioned above. It has virtually eliminated blowouts and improved my final quality.

What micron are you using for hash presses please sir? Are both layers the same or is one larger?

Do hash presses require different filters than flower squishes? thanks!

I want to try that too, have 2" x 3" 25micron Bags and also 160 micron bags that were with my dabpress. I want to start with 170 and low press, any Tips for packing? Cut the bags in pieces and wrap the material or put it in the bag? I Wanna try amounts of 1g or less for testing, so the bags will be too big, i could cut the end of the bag to make them smaller.

Put it on the plates for 10 minutes and then pre press then in the bag? I really want to start, but dont know how to pack for the first try... just have experience with bottletek style. Material is soft and dense.

1. Try: 1g @ 170*F dabpress, used low power -> 3 presses -> 0.21g return. Taste and look (dark) like the starting material with oily consistency. Diameter of 1 2x2 Lego Piece, wrapped in 25 micron (cut a sheet from a 2" x 3" bag), a little bigger than the 2x2 lego piece so i could completly wrap the whole piece in.

Maybe next time i could try more pressing power for more yield....

With just one g of material you are loosing a very high percentage of your return in the filter.

In my experience, a part will always stick to the filters, maybe like 0,2-0,3g.

Less material being pressed equals a higher percentage being lossed in the filter.

When pressing just one gram, having 0,2-0,3g stick to the filter(s) , means a loss of 40-60%(of your total return, if we count on a 50% return) . When pressing 10g, that same amount that sticks to the filter, only translates to 4-6% of your return being lossed to the filter(s).

To prevent blowouts, double bag with a 160 or 120 micron filter first, and the lower micron bag (I prefer the 20micron for pressing hash) around it.

In my experience there is no need to pre press with hash.

In a 2 by 4 filter I can press 50g of hash without any problem. And again, pressing less in multiple presses in stead of al in one, leads to more loss (in the multiple filters needed for pressing several times).

Temperature depends a lot in the starting material, but it should not be dificult to find a temp at which the rosin starts escaping with ease, or starts flowing. I think a good starting point is around 140f.

Pressure should be applied with care, especially at the start of the press when the material might not be totally up to temp.

Once rosin starts flowing you can slowly apply more pressure. No need to go high in pressure, just go slow. What pressure exactly, in my opinion, again mostly depends on the material being used.

In a way those 'sweet spots' (temp and pressure) will get easier to find with practice....

I always look for the blond, unpressed and not treated with heat (like almost al darker hash) hash as I find it gives me the best result. Also the truth is, it is the only hash I feel I can trust, as in it does not have oils mixed in or other stuff like pepermint oil or whatever they invent next(which will sometimes clearly show when pressed, for instance when the result stays way to liquid, even when cooling/freezing it) ...

In my experience, your average hash will give you a +-50% return. The worst I have pressed was 18%. The best, a ice water hash from marocco, gave a mindblowing 90+% return, of the most beautiful rosin that smelled exactly like the strain it was made from.

Should any of you feel like seeing some hash presses and flower presses, feel free to look me up on instagram under Lume_extracts

Thanks, i will take that advice to my flower Rosin too. In this case i just wanted to test if the material and filter works. I was a little afraid of blowouts or doing mistakes, so i packed amounts not more than 4g. (the press could do 7g flower) But maybe i should go for more and compare the yields...

To prevent blowouts, double bag with a 160 or 120 micron filter first, and the lower micron bag (I prefer the 20micron for pressing hash) around it.

Wouldn't that eat more rosin? Would you recommend it in any case or if necessary?

emperature depends a lot in the starting material, but it should not be dificult to find a temp at which the rosin starts escaping with ease, or starts flowing. I think a good starting point is around 140f.

Thanks, will give it a try next time!

I'm afraid the source material is not available to me. The material I have is already processed and can only be easily transferred in frozen condition.

Thank you @tepictoton for sharing knowledge.

my 1st experience with hashish was nepalese temple balls...
fond memories, would never have thought of pressing it.

I havent had hash in 40 yrs.70's. It was all good,black,blond.
I mean back then ,you took what you can get. Lucky the getting was good. With Colombian gold, and Mexicans that driped with resin..
But for ,I hate to say it I'm not 20 anymore.
Rosin presses were unheard of back then,just unimaginable back then. Oh I forgot,for some yrs high quality hash oil was around
