No worries. Happy to share some knowledge. Some people just use a therapeutic pad with fan blowing over (with cheese cloth to prevent dust or debris) it to slowly evap off the etoh. This should be done outside or in a very well ventilated space.
This is a basic trap - https://www.ebay.com/itm/30-200MM-G...pparatus-Chemistry-Lab-Glassware/331898097410
This is a better one - https://www.ebay.com/itm/500ml-lab-...l-light-catalytic-reactor-bottle/172883763915
This is a very good one, but takes a stand, clamps and other glassware - https://www.ebay.com/itm/1000ml-24-...le-Layer-Chemistry-Lab-Glassware/262660492627
All can be used dry as a liquid only trap, but if you add a cooling bath mixture (ice water or alcohol/dry ice) to the outside of the first or the interior of the second/third, you can condense some of the etoh vapor as well.
Two days is way too long, but if there is zero water content, it really does not mater. >0C Alcohol + non-frozen material with water content = picking up lots of crap other than cannabiniods and terpenoids. Since you are using Rosin as a starting material, you really don't have to worry about picking up too much chlorophyll and others, so I would say that as long as you purge the etoh, then it will be suitable for vaping.
A simple test to see if you have fully purged your extract is to place a small amount on a piece of metal and light it on fire. If it sparkles, then you still have ethanol in your extract and you need to keep purging.
Once again, many thanks.
My lab continues to grow (which is what happens to manics when they hook onto a hobby. LMAO) so I'll look into the cold trap. I just ordered some lab stands and clamps. Man, this stuff is expensive (if you get the good shit). Thanks again.
As for the rosin, itself.....
I often have stuff (samples) sitting in solvent for days or weeks. Oops LOL
I almost always use rosin as my starting point for everything I make (edibles, e-juice, etc) but just for my info, how long is long enough to soak flowers (buds) to completely extract but not over-extract?
OK, now for purging. This is really where I get lost. If I leave the alcohol, rosin mix in a glass dish it evaps down to nothing except the skin left behind which I scrap with a razor blade to collect. I'm pretty sure that means the alcohol is 100% gone. LOL I have tried the 'paper clip' test and I never get a spark from the finished product. It just melts. What I would really like to do is collect it BEFORE it gets to this point. It's so much more manageable.
If I left enough alcohol in it to collect it with a syringe and then put that in a cart, would I blow my head off?
It just seems a waste of time to take rosin which is thick, sticky and unmanageable for just about anything but a nail..... and run it though all these processes and filters, just to come up with an end product that is the same as what you started with.... thick, sticky and unmanageable.
So, I'm not sure if I am letting it evaporate TOO much or what.
I am going to do it again right now.....
I have some of that goopy back rosin that I mixed with 10ml of Everclear. It's been sitting for a few days. There's some white poop floating around in it. No idea what that is. Looks like fats/lipids like when I make e-juice.
Anyway, I'll filter that right now and evap off the alcohol.
OK, one last comment.
I am not doing this outside and I'm not doing it in a well ventilated room. It's not a closet but, again, it's not a fume hood...........
C'mon, we're talking about 10ml of alcohol. I would have to evap that into a bag and huff it for it to be dangerous.
In my opinion, I am in absolutely no danger working in a room with only 10ml of alcohol.
I am only talking about fumes. I do understand the fire danger present with even this small amount of flammable liquid. Especially with larger containers of flammable liquid nearby.
If anyone thinks I am wrong about the fumes, please feel free to bitch-slap me. You could be saving my life. LMAO
Once again, thank you very much.

I have well over 100 pieces of 24/40 glassware, so addiction is relative. Virtually everything that I have came from Deschem on ebay - https://stores.ebay.com/deschemsciencesupply/ Shipping is 7-10 days from China and rockstar level customer service. You should also search ebay for used "lab clamp lot" to get quality items on the cheap. I also had a welder friend make some custom lab stands that are better than anything you can buy.
It is more complicated, but the basic rule of thumb is that the colder that you extract, the longer you can soak, but this is to make purer shatter without picking up non-active ingredients. The shatter produced is suitable for all uses. Many people soak for 5-10 minutes but do 2-3 soakings of material.
Another form of alcohol extract is called Rick Simpson Oil (RSO) which uses room-temperature etoh and longer soaks. This produces a blackish extract is not suitable for vape but is used for topical treatment of cancer.
What you described is shatter. It varies in consistency depending on how much terpenes you have retained during purge. More terpenes equal more taffy like shatter at room temperature, and less equals shatter that is like glass. Purging is an art and you really need to read up to get a better grasp. I use vacuum distillation (cold boiling) with mantle and glassware to bulk remove etoh and then a vacuum oven to perform a low temperature (120-125F) purge.
I will say that the trick to loading carts (or even handling/storing shatter) is to heat the mixture to +120F. It will become a liquid that can be easily used in a syringe. If you want to use vape carts, first step to use a diluent (like Holy Terp Pure or True Terpenes) to make the mixture thinner.
10ml ain't shit, but if you want to have a fun little experiment, pour 10ml in a container (that you might not want to keep) and OUTSIDE throw a match on it. I would love to hear the results.
WFF
I'll never add my heat press extract to any solvent.

Nor you should, and I was going to qualify my statement above. This was about helping Ringo salvage his Rosin screw ups. It would be quite foolish (unless for medical reasons) to do an alcohol wash on well pressed rosin, primarily because you are going to lose a decent amount of terpenes during the etoh purge.
Pressing rosin undoubtedly changes some of the chemistry and composition and if you really want shatter (or to make vapable oil for carts), than you should skip the rosin and do an ethanol wash on the flowers.
Not trying to take away from this great thread. There are a great many benefits to solvent free techniques. Different strokes for different folks!
Agreed. I never have either (until now LOL). Really just experimenting more than anything.
The perfect solution for me would be to make the rosin a thinner consistancy WITHOUT diluting it with anything. Impossible? Sure seems like it.
If I could run straight rosin in a cartdidge, I would be thrilled.
Meanwhile, I enjoy the learning curve.
Another question for anyone.... Last time I used a standard coffee filter in the Buchner funnel. I have a ton of silkscreen fabric ranging from about 25 microns up to about 200 microns. Would any of this make a suitable filter for the funnel?

They make cartridges specifically for this, check out the W9-Tech Hurculese or the Atmos Kiln for some examples. The Hurculese is on the left, the O-phos (discontinued) in the middle both of those can handle pure rosin.
I think that is possible to efficiently filter rosin for pens, but I think it would involve using extremely dangerous solvents like ether that have a very low boiling point. Unless you have a proper lab environment, this stuff is too dangerous even to discuss.
Whatman filters are what you want - https://www.simada.co.il/images/filters/Whatman_filter_paper_guide_en.pdf You buy the diameter that fits your buchner. Some sizes are cheaper than others, and you might want to buy a bigger buchner just to make it easier (and cheaper) to work with commercial filters. You want a buchner with a "glass pore plate" and not a fritted disk - http://stores.ebay.com/Deschem-Science-Supply/Buchner-Funnel-/_i.html?_nkw=buchner+pore

My green crack x stardawg drips off a razor blade, very liquidy. probably work. I dont delve in pen tech so don't need to thin it ever.
the terpene fraction collected off a thc-a press would be suitable for cartridges without any added liquifiers.
i look forward to experimenting with that in the future.

@Reik. I have heard there are carts that will handle rosin. I even bought one. No way, this sticky ass rosin is going to get though those tiny holes in the one I bought. I'll check out the ones you posted. Thanks
@Water. My thought with the filter was to remove the big chunky parts and the resulting rosin would be thinner. Guess not. LOL
My rosin is almost never shatter unless I get the plates to hot. It's always sticky, and usually quite easy to collect. But, I have never had anything that would flow anything close to a syrup thickness.
I have to head out in a few. My band has a gig tonight.
Here is what I pressed last night from the Lemon OG Kush I recently harvested. Sure would love to put a gram of this in a cart and take it with me tonight. This is about the prettiest rosin I have pressed yet. LOL

I think the question should be what is in the chunky part? If it contains terpenes or cannabinoids, then you want it to be in the cart.
repress rosin through a fine filter such as coffee filter at very low temps and pressure. terps go through, all the thc-a stays behind if you do it low enough pressure and temperature. the re-extract is softer than the initial substance typically. but not really like a liquid as some strains can press out as.

most time I make hash, the rosin from the 25u bag almost always endup shattery or near shattery, the rosin from the 73u bag almost always is buttery or gooey.

BTW, I got the coffee filter technique from FarmerJoeParker on youtube,
https://www.youtube.com/watch?v=9HrFRbBf0P4
not that video but back then he had a lot of vids about it, he was using coffee filters with hair straighteners and he said in one of the video that he had won some competition with rosin.
At the time I thought, hey if he can win competition with coffee filters, it's gonna be good enough for me for a while! Rosin is very new to me in that I have only been making it for about 14-15 months but so far coffee filters, Mellitta's, are still doing it for me! If it aint broken, why fix it? I could see myself using some sort of lab grade filters a few years down the road, ... but for home use, do not be shy, coffee filters work great, way cheaper than any other over hyped filters you can buy online.

Good point. How would we know? I ran the Duqu test on both the stuff left on the filter and the stuff that passed through the filter. However, that only give THC and CBD content. Nothing on terps.

what were the results^? the temps I press (84 C) seem to allow about half the thc to pass through while slow pressing. I am thinking of using higher temps to get more thc in it. However, I think it is very strain dependent.
