I do all mine with cheap ISO hehe, I can't get 99% any more but have tried it in the past. I always use 91% now, typically the cheaper the better. Stew I evap at whatever temp my basement is at. In thew summer I was getting a completely dry evap in 24hrs, now that its colder it took about 30 hrs last week. I do my evaps with my pyrex dish sitting ontop of my dehumidifier. I've got a couple little pieces of foam that hold the dish nicely in place. I set a furnace filter over the top to keep crap out, but to allow the air from the dehumidifier to blow still. I set the dish so that its only covering half of the vents on top of the unit, and so some air is hitting the bottom of the dish, and the rest blows upwards and then over the dish as it hits the furnace filter above it. Qwisoking a member here does natural evaps just by blowing a fan at the surface of the dish. The natural evaps take longer, but by not heating it up I really feel like you get much better flavor, color, and smell specifically. When I first started making oil I was evaping over a double boiler and getting decent oil, and it always turned out with a gooey texture. After I started evaping more naturally, I started getting pure shatters, and pure waxes with flavors really true to the buds they came from.
I really think filtration is a HUGE part of getting a nice end product. I typically filter all my washes twice before I evap them. I need to get around to ordering some small micron filters to really get it clean. Heres a couple pics of some of my errl.
Here is some freshly scraped Sin's OG oil.
This one had pink streaks through it, it came from a purple Platinum Delight I had.
I believe this was Powernap bud sap which turned into wax in about 24hrs at room temp.
Finally an array of several of my concentrates. Bottom left: bubba kush oil that was heat evaped, Top left: Powernap wax, Top right: big piece is Cindy99 shatter, and the small piece is critical jack shatter, bottom right: Sin's OG crystals from the first picture.
Hope you guys enjoy
