So I've lurked hard on this forum since I bought my first vape over a year ago and have had all my questions answered without needing to post. The community here seems to be active, educated, and helpful; so I decided now is as good a time as any to join. A few weeks ago I was introduced to concentrates by a friend and haven't combusted since and I've only used my vaporizer a couple times. The clean, cerebral feeling is exactly what I always wanted from my medication. After one dab I'm completely satisfied, instead of taking multiple bong rips or hitting my vape for 5 to 10 minutes to achieve that level of medication. I plan on trying BHO in the future but for now I can only do QWISO. The first QWISO I tried was an oil. It was amber and tacky and I could see through it, it dabbed great and was very potent. An acquaintance of mine makes it but I can't get the same results. I do everything similarly except I air evap mine instead of using a double broiler like he does. I can't figure out why my QWISO comes out dusty and rock hard instead of oily and amber and it yeilds less (we use the same amount/quality of buds). I've made 4 batches now, 2 with abv, one with stems, shake and keif and my most recent one I used frozen, broken up buds. I've been trying to refine my method since my first run. My method - Small batch I froze 99% isopropyl alcohol and 3.5g of good buds for almost a day. The buds werent super dank but still really good, crystally headies . The buds were broken up, not ground. I set up 4 different jars each with a single unbleached coffee filter that I submerged in alcohol prior to the wash in hopes to reduce the amount of thc-ridden alcohol soaked up by the filters. I used a 5th jar that I put the bud and alcohol in and a small kitchen strainer so that the alcohol would pour out fast, without drastically impacting the wash time. Less than a minute lapsed from the time I removed the buds and alcohol from the freezer and put them in the jar together. After I added the alcohol I swirled and shook lightly for about 10 seconds and then strained the liquid into my first jar with a coffee filter. The buds soaked for less than 15 seconds. I then repeated the wash 3 more times, each time I shook more violently and for longer. My fourth was was between 30 and 45 seconds, I stopped keeping track after my second wash. I then emptied my first jar into a large glass dish and my second jar into another dish. The 3rd and 4th washes were combined, sealed, and allowed to evap at a later time. My first wash yielded almost nothing. The second wash yielded much more but it still wasn't that light amber colored oil that I was hoping for. I scraped the glass dish after it had air evaped for almost 24 hours, I had an air purifier blowing air onto it to speed up evap and to reduce the amount of dust or hair that the dish could pick up. When scraped it turned into this fine white/light green dust like the first wash. (lost some image quality when resized) I then heated the pile up with a candle warmer and Intel cpu heatsink. I heated it up just enough to melt it so that I could form it into a single piece so that it was easier to handle. Only my second wash is pictured, didn't get any from the other washes. Wearing gloves during the scraping process made things so much easier. No sticky fingers, no qwiso absorbed/melted by my hand. The qwiso is hard and shatters, it sounds like a rock when I drop it on the glass pan. It completely melts when dropped on my nail and is extremely potent, smallest dab blew me away. Overall I'm happy with my product, especially considering that this is my first run with buds but I want to increase my yeild and avoid the flaky hash because it gets everywhere. How do I get that light amber color and tacky tree sap consistency with a short wash? I know its a long ass post, but any help is greatly appreciated.
