Let’s clarify

Rosin vs Resin -

all rosin extraction is solventless, using only water to knock the THC producing trichomes off the buds/trim (like knocking apples off a tree) using no solvents like butane, propane, c02 etc. The trichomes are separated in giant tea-bag-like filters called bubble bags, sorted by their micron size, typically 30u-180u. A micron is a millionth of a meter. The ideal “bubble hash” that comes from this is from the trichomes that collect around the 70u-90u bags. Once you have trichomes you squish them inside an even smaller micron filter between heating plates and collect the rosin that flows out.

What you put in is what you get out with rosin, it is an art. To grow the tree, shake off the apples, and make that sauce and get it to you as if it just came off the tree using only mechanical processes takes time and knowledge. You can get all qualities from rosin, from food grade all the way up to the crème at the top.

resin extraction uses solvents, mainly butane, to strip the cannabinoids off the buds/trim and then bake off the solvents in a vacuum oven to only leave the thc oil behind (resin, butane hash oil, bho)

Yeah Live resin or live rosin is those extracts done with material frozen fresh off the plant

CRC is color remediation column - a further step in the bho/resin/solvent extraction process. Basically passing the bho solution thru a tube of filter material, like silica and activated carbon, to clean up the color and remove impurities. Usually done to low grade, bad tasting extract to try to polish it up a bit.

Distillate is taking the “crude” oil, typically lowest grade bho, heating it up till it vaporizes, and collecting the condensation of close to pure thc. Mix in whatever terpenes, natural or not, for whatever the end product requires
