Rosin versus resin
Rosin versus resin:
Resin can be any solid or highly viscious substance from plants, or synthetic analogues,
that will set into a hard lacquer or enamel-like finish.
Rosin typically refers to one of a few specific resins.
For example
- Rosin on on violin bows is often often pine tree sap, heated and concentrated.
- rosin/resin soldering flux
- THC rosin is heated, concentrated sap from the cannabis plant.
- though there is a more specific resin/rosin distinction in this context
