i to use parchment paper to press and store mine in. then the folded parchment paper goes into a jar.
i use 99% iso and have the larf bud or trim in a metal coffee filter inside a tea strainer. then i will pour the iso over that into a wide mouthed mason jar. then i move the filter system w the product inside to another wide mouth jar and pour the already poured alcohol through it again. i normally do this 3-5 times depending on how cold things stay. then with the golden iso i filter that through a coffee filter twice and then pour onto pyrex to dry. i wait for it to completely dry before trying to scrape and i do not use heat.
with the leftover material that i used to pour over, i will usually put that into a mason jar then shake the shit out of it for 30sec and then start to filter, once w the metal to get the plant material seperated asap, then with the coffee filters. so 2 washes altogether. i pour my 2nd wash into a 2nd pyrex and just wait for it to evaporate. at this point i toss any left over plant material, although i could probably do a 3rd wash if i really wanted. ill try to get some pics up soon. its a hassle to get them off my phone to laptop for upload.
ive found when i try to use heat to evaporate i will end up with a sappy substance or shatter that will turn to budder or wax within a few days. i just let it airdry completely and i end up with beautiful crystal flakes a normally press into shatter. sometimes i will leave it unpressed if i want to use it for "sprinkles" over a bowl. its cool watching the hash that isnt pressed melt away to nothing
