New extraction technique? Rosin tech?

I just use a flat iron .... spent some time with schmoe this weekend ... hes had a t shirt press ... been through two rosintech presses and prefers his flatiron.... i think there is still a ways to go with this tech ... my flatiron works surprisingly well :) For under 30 bucks, i just havent seen anything that has impressed me enough to invest more yet. Bubble and kief has been giving me enough to keep the "chimney" going :)

Just an FYI for you people who are using mesh......

I bought some bulk silkscreen mesh in a roll about 5 feet wide by about 20 feet long for under $50 on Ebay and I have been using it for years to make pollen boxes, bubble bags, sift shakers, etc. It has always worked great and it is about 1/10th the cost of bubble bags, pressing cloths and all the other "cannabis" related uses. Not sure how pricing is today but I'll bet it's still way cheaper.

I HAVE NOT tried it under pressing conditions. I ASS -u- ME it is the same product as the bubble bags, etc. but I can't say for sure. Next time I press, I'll run a few pucks through the mesh. I have tried it for sifting and water hash and it has always worked fantastic for those purposes.

Just FYI in case anyone is using this stuff at the rate I am going through parchment. LOL

EDIT: I just checked the prices on Ebay and they are about the same as they were when I bought mine. Way way cheaper than buying "cannabis" mesh. Also, remember that the silkscreen world uses mesh sizes and NOT micron ratings. If you plan to buy bulk silkscreen do a Google of "Convert Mesh to Micron" and you'll learn what you need to know.

Another EDIT: Why is the word, micron always in italics???? Unless, of course it is put in quotes .... "micron". LOL

Def not a new tech.

been doing this since the mid 80's with parchment paper and a iron or frying pan using a washrag as a heat transfer blanket.

just place your kif wrapped in parchment folded in a wash cloth apply heat iron of skillet press with spatula if using the pan.
using a iron is the best way because you can set the heat to 180f and not loose your terps.
old school growers have been doing this for a long time
it produces beautiful oil, when cleaned up with etoh and you get amber.

Why would you need to clean it up with etoh? The whole point is for it to be a solvent less extract. If you are gonna do that you might as well just make BHO, and make shatter with etoh. No way on earth I would take the time to make Rosin, then introduce anything to it. I get zero contaminant with flower straight on parchment and tea bags filters Kief or hash. Save your Everclear for something else.

Yes it is. We just made it up at the beginning of this thread. Before we did it, nobody else ever did it ever anywhere in the whole world.

We invented rosin. It's ours. It belongs to us. And, you can't have any. Nyah nyah.

LMAO..... 3 members found my post above, "helpful". OK, you 3 guys need to seek out the assistance a mental health professional. Immediately. LMAO

OK, new experiment. Actually 2 experiments. Cold and humidity.

First test. All variables same as all my presses. 1 gram pucks. Same setup. Same pressure (about the max from a 6 ton press) and heat (about 230F). The different variable this time is that I made the pucks yesterday and put them in the freezer overnight.

Appearance of the pucks from the freezer was no different than unfrozen. No frost or water was apparent. A little frost on the baggie.

I pressed them with the same variables as unfrozen pucks and I am excited to say that..... there's no difference in any way that I could see. LMAO

No sizzle. No steam. The rosin was no more or less runny. I was quite surprised that I could not find a single difference between frozen and unfrozen pucks. Very odd.

However........... next experiment.

I did find a few buds that I left out on my bench from a few days ago. Humidity here is in the low teens or single digit and the buds were so dry that they crumbled to the touch.

I tried to pack my puck-maker but the buds just crumbled into dust. I packed a gram of the dust into the puck-maker and made a puck.

I pressed the puck under the same variables as always (press for 30 seconds @ 230F) and the rosin came out so dark it was almost black. The puck broke through the parchment and the pot and rosin was all over the place.

The next press, I did at about 1/2 of the pressure. Same temp and duration.

The rosin was very dark again and the puck broke through the parchment again (this almost NEVER happens to me with me 62% to 69% stuff that I usually press).

So, I made another puck and pressed it at about 1/5th of the pressure and low and behold a river of rosin came flowing out. And, the parchment didn't break through this time. I did a few more pucks at low pressure and the quantity of return was noticeably different even to the naked eye.

The rosin was still too dark for me so I'll try some tests at lower temps and duration but I can definitely see a need for some serious testing on proper humidity levels for rosin processing. I would have never guess drier to be better but it might turn out that way. These dried out pucks definitely produced more yield than the 62% to 69% material.

I have several methods of controlling humidity in mind and I'll go from single digits to 80% or 90% and see what I get.

Rosin on doods. :)

i just recently started doing this. I just purchased a 1ton press to do small quantities of bubble hash. Im in between harvests now so ill need to wait to see how it works with bubble.

my set up is simple and costed about $70. I got 2 6x6x.25" low carbon steel plates which i heat to 250degree in a microwave oven. One plate on the bottom, extract supplies, then the other hot plate on top and i just press w 1ton. Was thinking about buying an extension pole, about 15", to increase pressure and stability of the press.

Ive been making bubble and dissolving in ISO, triple filter and purge. I think im going to get a better final product when i do dry ice extraction and a 1ton heat press.

I did two 1 gram bud samples over the weekend and was pleased with the results. To me it doesnt make any sense pressing buds that could otherwise be smoked, but this method will definitely make kief or hash more pure and "dabbable"

Played with the new press today, had some blowouts, but all in all i am impressed, it held the heat very even and was easy to use. This is made with fresh kief...

Been playing around with a t shirt press, and finally getting some good results.

Flowers can't be piled up and pressed. They can't really be done in bulk, IMO. I set about 20 nugs about 2" apart and press that. A little faster than an iron, but not much.

Bubble hash is really where it's at. I made my own bag with some old bubble bags pressing pads, and loaded one up with bubble. The returns were very nice, and the product was full on shatter.

After the holiday, and when my actual bubble rosin bags come, I will take a picture or two.

Everytime I press hash it always comes out shattery and a pain in the ass to collect. I press for 10 seconds on the lowest setting of a hair iron. I'm wondering if I should press at a hotter temp or for longer? I've tried quick presses but its the same result. Thoughts?

Same with me, strait shatter.

I use a heat gun. Just a cheepy used for drying paint and such. Just 2-5 seconds and the shatter turns to goo. Goes back to shatter, so keep the heat gun handy.:tiphat:
