Scraping Hash.....

Hey all,my hash has evaporated and im having the hardest fucking time scraping it up....its iso hash,glass dish.Any ideas?

razor blade .... so what type of (bud,cuttings,stems) did you use and how much of it + how many grams of hash you get

ive been using a razor blade,its not working good...I used a mason jar full of my ladies fan leaves,I didnt get much at all off the dish,but there ton of residue left.

my only idea is get some rubbing alch.. and put a piec or wax paper in a bowl and lit it evaporate again...and what is the iso method i only know butane achl.. and bubble hash

soak it in iso,then let it evaporate.

how do you get hash?
