// Definition
Color Remediation Chromatography (CRC) is a post-extraction filtration technique using media like diatomaceous earth, silica, and activated carbon to remove pigments and impurities from BHO, producing lighter-colored concentrates. Oregon outlawed specific CRC media while Washington still permits them. Critics argue CRC masks poor-quality input material and leaves an unpleasant aftertaste that strips terpenes.
// From the Episode
Dr. Allison reported that nearly every BHO entry she judged at the Washington Craft Cup was CRC-processed and tasted unpleasant. Bubbleman noted that BHO never fully recovered from the 'blow' that rosin dealt it, and CRC further damaged BHO's reputation. Nick Bradley clarified Oregon outlawed specific media rather than CRC itself. The discussion tied into broader themes about solventless purity — bubble hash and rosin were presented as superior sacramental forms of the plant.
