Test Artifacts

Our lab maintains a dedicated collection of test artifacts designed to support training, research, and the practical demonstration of scientific examination techniques. Unlike case studies, which involve real artworks, these artifacts are purpose-built objects that simulate specific materials, pigments, structures, and degradation patterns. They allow us to test, compare, and validate our instruments and methods — from imaging to spectroscopy, including Technical Photography, Raman spectroscopy, XRF spectroscopy, and more.

Test artifacts are essential tools for teaching and experimentation. Because their composition is known and reproducible, they offer controlled conditions to evaluate instrument performance, understand method limitations, and practice correct data interpretation. They also provide a safe environment to explore scenarios that cannot be performed on real artworks — such as accelerated aging, repeated measurements, or destructive sampling in selected cases.

Working with these reference objects helps build a solid foundation before approaching historical or valuable materials. They allow students, researchers, and professionals to observe how different analytical techniques respond to specific pigments, binders, substrates, or artificial defects, and how complementary methods can be combined to obtain a clearer and more accurate understanding of an object.

We believe that learning with test artifacts is a crucial step toward mastering imaging and spectroscopy. By offering predictable yet diverse examples, they help develop technical competence, confidence in handling instruments, and the critical skills needed to interpret results correctly.

This section presents the test artifacts we use in our training programs, instrument demonstrations, and internal research activities. We periodically expand this collection as we develop new materials and add more complex scenarios. Keep an eye on this page for updates on the latest tools and experimental models from our lab.
