// Definition
The process by which THC-A molecules in dried trichome heads begin forming crystalline lattice structures over time, similar to rock candy formation. When oil from a burst trichome contacts intact heads, it creates nucleation points that initiate a chain reaction of crystallization throughout the hash.
// From the Episode
Mark Scialdone provides a detailed explanation in Ep 028 of how crystallization occurs in dry sift. Mechanically removed trichomes dehydrate and their waxy coatings coagulate, creating nucleation points. THC-A is described as 'always static, always looking for carbon to grab onto.' Traditional Afghan hashmakers exploited this by burying loose sift 3 feet underground for 1-2 years before pressing, maintaining a consistent 56 degrees Fahrenheit.
