Try as I might, the material remains somewhat sticky. After several more hours pouring through threads I found what I believe to be the main issue. The trim I have thus far been running is amazing. It's closer to cured than dry through and still squishes in my hands. I have found that when looking for a harder or shatter like consistency, it is essential to have your material very dry. It also increases yield and decreases the amount of plant matter the solvent will pull. I have a dehydrator but looked further into it and found that terps degrade even at room temp, dehydrating your material will speed the process but also change the smell of your final product(due to loss of terps as most dehydrators run between 95-140). I have found an excellent alternative to this in my vacuum chamber! Put a few ounces in, pull 25-29 for as long as it takes, usually only an hour or two. This preserves more of those precious terps and eliminates the need for a dehydrator. I also changed my set up. My chamber will sit in a silica sand bath on my griddle or hot plate, oil temp will be tested @ 90 first. I will run full vac in 20-30 minute intervals degassing the chamber in between. I plan to flip the slab once and do those cycles for 3-5 hours(longer if needed). I will also test different runs in 10 degree increments to show what happens at each temperature. Is it ok to add a coffee filter under my 50 micron screen in my CLS? I wonder also if 50 micron lets many of the sticky lipids and waxes through. My original failure I used a 50 micron screen and didn't see the tiny holes until after I believe that is another factor that determined the consistency of that extract. Anyways my point is, do not be naïve like me and overlook such a simple aspect. I felt it was dry but did not want to loose taste and failed to see the logic in moist material equaling moist extract.
I suggest packing the coffee filters between the screen and the plant material, using the screen to simply support the filters.
Besides residual solvents, and water, another thing that loosens up shatter, so that it isn't brittle at room temperature, is monoterpenes.
Monoterpenes are alcohols, ethers, aldehydes, ketones, esters, and carboxylic acids, typically with high vapor pressure even at ambient, which is how they stink up a room right through double baggies so easily, even though they are significantly below their boiling points.
They are easy to extract if they are still there after drying and curing, and the most common stumbling block is holding on to them while purging residual solvent. All moot of course if they are lost during drying and curing.
The easiest way I've found to produce pristine double gorgeous museum quality bragging rights shatter for photographs, is use fully cured material.
The easiest way I've found to produce aromatic tasty concentrates, is not get caught up in fads or semantics, and consider shatter to include pull and snap. Pull and snap is what you get when you have a pristine double gorgeous museum quality bragging rights shatter with more residual monoterpenes remaining and acting as a solvent.
One of the charms of pull and snap, is that besides having more bouquet and flavor, and being just as gorgeous to cast our eyes upon as brittle shatter, it is not as prone to send shards flying about the room when you are trying to part off a piece with a cold dabbing tool.
