STAR LABSeparate three questions: what material is described, which method family is named, and what evidence accompanies the record.
A map of the terminology
Solventless is an umbrella term. Dry sift, ice-water hash and rosin describe different material or method categories within that discussion. Health Canada explicitly distinguishes mechanical actions that separate trichomes or resin from processing involving organic solvents. [1]
The following comparison explains the physical ideas behind the names. It is not an operating procedure: the goal is to make an article, label or research description easier to understand.
Compare the physical principles
| Term | Broad principle | What the term identifies |
|---|---|---|
| Dry sift | Mechanical separation of trichome-rich particles from dry material | A particulate material and separation category |
| Ice-water hash | Physical separation associated with ice and water | A hash category; also called bubble hash |
| Rosin | Mechanical expression involving heat and pressure | A resinous material and process category |
These broad descriptions follow the concentrate terminology outlined by BC Cannabis Stores. They do not supply operating settings or assign a quality grade. [2]
Where “live hash rosin” fits
The words carry different pieces of information. “Live” refers to source history, “hash” identifies a material relationship, and “rosin” identifies the concentrate category. Read the live rosin versus live resin comparison for those definitions.
A name can be informative without answering every question. It does not supply the batch identity, measured composition or source of an aroma description. Those details belong in separate fields, where they can be checked.
Keep method, measurement and result apart
A process description explains an approach. A micron value is a length specification or measurement that needs a defined object. A certificate of analysis reports results for a sample. None is a substitute for the others.
For a clearer comparison, put each record into three columns: category, evidence available and unresolved questions. If one description includes a test report and another does not, describe that documentation difference precisely. Avoid inventing a chemical or quality difference to fill the gap.
A short vocabulary check
Are hash and rosin the same word?
No. They describe distinct material categories; “hash rosin” expresses a relationship between them.
Does “live” name a solventless method?
No. It describes source history and also appears in the solvent-based term “live resin.”
Does a smaller micron number establish better quality?
No. A length alone cannot establish composition, aroma or contaminant status.
