Well the time has come for me to sit down and type this out the best i can.......
SUPPLIES:
9"x13" pyrex
8"x8" pyrex
electric griddle
filtration of some sort of filtration (pictured here is 50 micron screen with hair tie on jar , also you can use coffee filters, i really like the mesh ones)
strainer
91% or higher iso alcohol( enough to cover material twice, for one ounce trim i use one 32 oz bottle)
material to run (in this example i have 26.8 grams)
razor blade or scraper of some sort( i prefer the straight blades for scrapers)
fan
2- 1 quart large mouth mason jars
GETTING STARTED:
To begin with set griddle on a level surface where it can be adequately vented using a fan to pull air across pan an draw fumes away while evaporating (do not breathe evaporating fumes! you will get a headache). Once you have picked a nice level surface with good ventilation to set you griddle on its time to set the 9x13 pyrex ontop griddle fill half way with water and turn griddle on to full heat of 400f. While it comes up to temperature is when i do my pouring and preparation work making sure mason jars and 8x8 pyrex dish are free off any dust and contaminants. If your trim is fresh throw it in the oven for 30 minutes at 170f(or as low as oven will go,dry weight 26.8g)I used to keep everything cold in freezer but have long since abandoned this practice and instead use the oven dry and quick wash to keep final product gold and not green.
TIME TO MAKE GOLD:
Alright we got out water heating up on griddle,our containers are all clean, and our material is ready to be processed time to get to business. Take your material and put it all into one of the mason jars. Take iso and pour into jar making sure to fully cover material. Gently twist jars back and forth in "swishing" motion, think like a washing machine on gentle cycle lol. Swish for 30 seconds and then take your strainer over top of the jar and carefully dump liquid thru strainer into other jar. REPEAT rinse and strain of material(i always do 2 quick washes some do more). Take the jar that is full of your gold liquid and put 50micron filter or coffee filter over top of mason jar with a hair tie. Slowly poor the liquid into the 8x8 pyrex, if using unbleached coffee filter this part can take a minute so i recommend the mesh one or the 50 micron screen.
LETS GET COOKING:
Ok water bath should be good and warm now. Carefully place 8x8 pyrex into water bath, being careful not to splash water. Turn fan on and let the magic start. Depending on the density of the trichs on your material you may start to see swirls in the oil as it evaporates (i love watching this). As the evaporating oil gets lower i always carefully swish it around in pan, not sure if this helps even evaporation but i do it anyways. The 32oz of iso will take about 2.5-3 hours to evaporate off, i always just check back every half hour to swish oil and check water level(you may need to add water if water bath gets low). Once the liquid is evaporated and you are left with just oil turn the heat off and let oil remain in hot water bath for another 20 minutes.
