just found this ... anyone agree with it ?
the difference is, the soft squidgy black hash is made from trichs that are taken from the plant while its still alive and in full bloom (notice how sticky a fresh resinous plant is).. traditionally the farmer rubs his hands over all the plants in the field (or nowadays i think they walk through the field wearing a leather apron), collecting lots of sticky resin.. he scrapes this off and rolls into a ball. its usually mixed with some local ingredients like tea or whatever is tradionally used in that region, black hash isnt usually contaminated with the crap they put in soapbar, its made to the same recipe/methods by farmers who have being do so for generations and each hash is disticitive to that region..like fine cheeses.
the solid hashes are pressed trichromes, from a cut and dried plant. the trichromes have lost thier water molecule and are no longer sticky. they need to be pressed or bound together. as the water molecule isnt there anymore, several differences in the dried trichrome give it a different colour and taste.
