Hash is unbroken trich heads (and some contaminant, plant matter ect)gathered by dry sifting, ice & water extraction, or even hand rub, untouched by chemical solvents.
A nice crossover product that is sort of in the middle is rosin. If you rub some dryish hash on a hot pyrex plate, it leaves behind a bit of an oily residue (rosin) on the pyrex that can be scraped up and smoked in a similar manner to a solid oil, having used zero solvents. I haven't tried this myself yet, but its a technique I learned about from Hash_bean420. I think there may even be a post in these very forums on it.
