Colophony, also known as rosin, is a solid form of resin obtained from pine trees and other conifers. It is a brittle, glassy substance that becomes sticky when heated and is used in various applications, including as a grip for bowstrings, in varnishes and inks, and as an ingredient in some types of adhesives. In certain contexts, colophony can also refer to the historical term for the concluding part of a manuscript or a book, which includes information about the work’s publication.
