try re-sifting your dry sifted resin to improve potency and meltability
after the resin has been worked through the 1, 2 or 3 meshes, I feel it's worthwhile to re-sift the resin heads through the (tapped clean) screens again
stop re-sifting the resin when 90% of it has passed through...the remaining 10% on top of the mesh will be mostly broken up plant matter and can be set aside.
re-sift the resin gently 3 times, remove 10% the first sift, 5% for the 2nd sift and less again for each subsequent re-sifting..but just once through the same screen will noticeably improve the purity/quality/ "intenseness" of the high
triple sifting your resin could mean the difference between hash that sizzles and hash that bubbles..or somewhere inbetween
