// Definition
High-purity THCA crystals produced through mechanical separation of rosin, without the use of any chemical solvents. The process involves pressing rosin at various temperatures to fractionate terpenes away from the THCA, then melting and reforming the remaining THCA powder into crystalline shapes.
// From the Episode
Caitlyn from High Fidelity, one of the only makers in Canada producing solventless diamonds commercially, detailed her process. She presses rosin at temperatures between 130-220F across multiple rounds, collecting terpene fractions separately. The remaining THCA powder tests at 91% THC with 0.02% terpenes, while the sauce fraction tests at 50% THC with 18% terpenes. She reduced process loss from 32% to 8% through iterative refinement.
