![]() ![]() ![]() After a run through the CRC, a finished concentrate will retain most of its cannabinoids and terpenes but look more like a wet packet of table sugar than a dollop of honey or a sheet of gold-tinted glass. By packing T5 bentonite clay, silica gel and Magnesol ( aka frying oil filter powder) into a filter column, extractors can turn dark or amber extracts into white gold. To achieve that pigment-washing effect, CRC systems use a three-substance filtration combination. The popular processing method adds a step to the traditional BHO recipe by creating a last-step filtration column that pulls out even more imperfections, and most notably, removes most if not all of the concentrate's color. What Is CRC Extraction? via InstagramĬRC stands for color remediation column. Over the past couple of years though, cannabis extractors have added a new step to the BHO production process to shine up concentrates and make them look as pure as possible - CRC. These days, extract artists in states like California and Colorado use sophisticated lab equipment to make explosions a thing of the past and remove solvents past state-mandated standards. Widespread legalization solved many of those problems. Beyond their flammability, early BHO was notorious for containing residual quantities of butane, leaving users to vaporize not only THC and terpenes but unwanted volatile gasses. CRC SHATTER SERIESThose backyard and garage setups quickly became infamous for exploding, creating a series of high-profile news stories about the dangers of BHO. In the early days of the concentrates movement, making BHO was largely the territory of home chemists using crude, open blasting methods to make wax without a closed-loop system. On the flip side, a dark, runny or liquid oil is the product of poor extraction tech, low-quality shake or both. A tan or golden extract that is stable to the touch is usually the result of a quality BHO production process using a top-shelf flower. The final consistency, color, and quality of a BHO concentrate are largely due to the potency and freshness of the starting material along with the specifics of the extraction process. Once the butane is run through the bud or trim, a closed-loop system uses specific temperature control and vacuum pressure to filter out impurities and produce the various consistencies of extract that dab consumers love so much. ![]() To produce BHO wax, budder, shatter, sugar and other sought-after dabs, cannabis extractors use butane as a solvent to strip the valuable cannabinoids and terpenes from the plant matter. Whether you know it or not, if you've done a dab over the past 10 or so years, there's a pretty good chance that you've consumed butane hash oil - aka BHO. The Basics of Butane Hash Oil and BHO Extraction Unsplash CRC SHATTER HOW TOSo what is CRC extraction? And for that matter, what is BHO? In this piece, we'll break down both of those hot acronyms, covering everything you need to know about how to make cannabis concentrates, why extract manufacturers and sellers alike have fallen in love with CRC products, and what you should look for - and look out for - when purchasing the latest generation of dabs. One of the newest forms of concentrate is a pale yellow, white or almost clear form of butane hash oil made using a process called CRC, or color remediation column. After almost a decade of popularity, cannabis extracts made for dabbing have evolved from open-blasted butane extraction to highly technical closed-loop systems and solventless pressing methods.
