I think anyone that jars bud gets Tricomes stuck on the glass. You can dry sift as suggested but some will always stick if you Are growing Good Bud, so Props for the problem!
I agree with above poster, get ever clear say 1/2 cup pour into jar and shake till glass is Clean.
Pour everclear into next jar and repeat to each jar.
I am pretty sure you will get them nice and clean (I do 12 jars w 1/2 cup) , when finish pour it into a Pyrex dish with a flat bottom.
Then place dish on seedling mat or heating pad AWAY from Flame, No Smoking.
We don't want you hurt.
I put in my garage for two days on a seedling mat and the 1/2 cup liquid will evaporate.
some people scrape the dish when sticky, I let dish come to room temp then place in freezer.
when solid scrape slowly so it does pop and go flying, voila basic shatter!
