"Paint Technology and Tests" by Henry A. Gardner is a scientific publication written in the early 20th century. The work focuses on the technical aspects of paint formulation, particularly the properties and testing of various materials used in paint production, such as oils, pigments, and driers. This resource serves as a comprehensive reference for professionals in paint manufacturing and application, including engineers, painters, and students looking to better understand paint technology. The opening of the text establishes a clear purpose: to provide factual information about the durability and efficacy of different painting materials, counteracting prevalent biases towards traditional products. Gardner emphasizes the necessity for thorough research and testing to illuminate the characteristics of paint components, thus facilitating informed decision-making in the industry. The preface also highlights collaboration with various professional organizations to enhance the study of paint properties, setting the stage for subsequent detailed explorations of oils, driers, and their effects on drying times and film formation in various environmental conditions.
