*La chaux* is a concise French-language nonfiction title examining lime as a material and its practical applications. Aimed at general readers, students, and anyone interested in building materials or industrial processes, it presents the basics of lime in accessible language, including its production and behavior, with attention to where it is used. The book’s emphasis on “ses utilisations” suggests a practical orientation, connecting the material to construction, maintenance, agriculture, and related trades. With 73 pages, the work appears to function as a compact reference or educational guide rather than an exhaustive technical treatise, making it useful for introductory research into the material’s everyday utility.
