Comparative Examinations of Cleaned Paint Surfaces


Book Description

This volume explains four different methods for examining paint surfaces. It adopts several examination tools to compare untreated and treated surfaces of oil and acrylic paints, such as scanning electron microscopy (SEM), computer-aided laser profilometry, environmental scanning electron microscopy (ESEM) and 3D-measurement technology. Samples of historic oil paints, contemporary oil paints, and modern acrylic paints, are examined within, using subjective and objective measurements, to reveal ideal surface cleaning systems and methods for painting surfaces. The book presents tests of several surface active materials on oil paints and acrylic paint surfaces, including latex sponges and demineralized water, saliva, cellulose ethers, anionic and nonionic detergents, and microporous sponges.







Issues in Contemporary Oil Paint


Book Description

This volume represents 27 peer-reviewed papers presented at the ICOP 2013 symposium which will help conservators and curators recognise problems and interpret visual changes on paintings, which in turn give a more solid basis for decisions on the treatment of these paintings. The subject matter ranges from developments of paint technology, working methods of individual artists, through characterisation of paints and paint surfaces, paint degradation vs. long time stability, to observations of issues in collections, cleaning and other treatment issues as well as new conservation approaches.







Handbook of Trace Evidence Analysis


Book Description

Covers new trace evidence techniques and expanding areas of analysis, along with key theory and applications Developed around the need for updated information in the disciplines of trace evidence the Handbook of Trace Evidence Analysis focuses on the increasing awareness and need for validation, modern methods for addressing and controlling contamination, the shift towards incorporating statistical analyses into the interpretation phase and cutting edge research into new forensic science methods and their application. Beginning with an overview of the topic and discussing the important role that information derived from trace materials can provide during investigations, the book then presents chapters on key techniques. The first being the critical nature of microscopy, and the methods employed for the recognition, collection, and preservation of trace evidence. Subsequent chapters review the core disciplines of trace evidence examination: paints and polymers, hairs, fibers and textiles and glass. Each chapter contains in-depth discussions on the origin of the materials involved, including any natural or synthetic processes involved in their production, the nuances involved in their detection, and the methods of analysis that are used to extract valuable information from samples. In addition, suggested workflows in method and testing selections, as well as addressing specific scientific challenges as well as the limitations of knowledge on the transfer, persistence and background abundance of trace materials are discussed. The book ends by examining the interpretation of trace evidence findings from a historical perspective and examining the methods that are currently being developed. Provides an in-depth introduction to the general area of trace evidence and discusses current and new techniques Consolidates trace evidence and materials categories of testing into one reference series Offers a detailed focus on technical approaches and guidelines to trace evidence Includes analytical schemes/workflows and valuable guides for the interpretation of data and results The Handbook of Trace Evidence will appeal to forensic science academics, students, and practitioners in the trace evidence and materials science disciplines, as well as DNA analysts, toxicologists, forensic anthropologists, crime laboratory managers, criminal justice students and practitioners, and legal professionals. It would also be a valuable resource for every crime laboratory reference library.
