Web Non Destructive Testing In The Preservation Toolbox

  1. 1. Non-Destructive Evaluation in the Preservation Toolbox by Mary F. Striegel National Center for Preservation Technology and Training
  2. 2. Cultural heritage is deteriorating from natural and manmade causes.
  3. 3. NCPTT was created to develop or transfer new technologies to the world of historic preservation.
  4. 4. Without nondestructive testing of Cultural Heritage, appropriate treatments cannot be made.
  5. 5. New advances in NDT hold the promise of new ways to study and conserve our cultural heritage.
  6. 6. What is Cultural Heritage? KellyMullaney, “Cultural Exhibits during Hispanic Heritage Family Day,” October 21, 2008, online image, flickr.
  7. 7. Architectural buildings and structures. . .
  8. 8. Archeological sites and collections. . .
  9. 9. Art or historical collections. . .
  10. 10. Parks, gardens and other landscapes can all be considered cultural heritage.
  11. 11. Cultural resources are subjected to many agents of deterioration.
  12. 12. Natural decay goes unchecked from lack of understanding of chemical/physical properties.
  13. 13. Well-meaning but inappropriate maintenance leads to loss of materials.
  14. 14. Natural disasters have devastating effects on cultural resources.
  15. 15. Manmade destruction results from lack of understanding or appreciation of resources.
  16. 16. Nondestructive testing methods can help to understand the physical aspects of cultural heritage.
  17. 17. Eddy Current Testing
  18. 18. Eddy current testing provides a way to study gilded surfaces
  19. 19. Infrared Thermography
  20. 20. Infrared Thermography is used to monitor the consolidation of voids and delamination on stone artifacts in real time. Evaluation of Infrared Thermography for Monitoring the Consolidation of Voids and Delamination on Stone Artifacts in Real Time, 2002 PTT Grant, Nelson Atkins Museum
  21. 21. Infrared Thermography is used to identify presence of termites in St. Alphonsus Church, New Orleans.
  22. 22. Laser speckle interferometry The Getty Conservation Institute Herculaneum Project http://www.getty.edu/ conservation/science/ herculaneum/index.html Accessed 3/12/2009
  23. 23. Laser Speckle Interferometry detects stucco detachment in wall paintings.
  24. 24. The method follows the injection of grout as a corrective treatment. The Getty Conservation Institute Herculaneum Project http://www.getty.edu/ conservation/science/ herculaneum/index.html Accessed 3/12/2009
  25. 25. Nondestructive testing methods provide a way to look at the chemical nature of cultural heritage.
  26. 26. NMR (nuclear magnetic resonance) MOUSE
  27. 27. NMR MOUSE can help follow deterioration of pigments in paintings.
  28. 28. Portable XRF
  29. 29. Copper Artifacts from the Gahagan Site, Northwestern State University of LA pXRF is used to determine provenance of metal objects.
  30. 30. The technique can be used to study chemical changes after treatments.
  31. 31. A new portable XRD/XRF instrument has been built for the study of works of art.
  32. 32. PORTABLE XRD/XRF INSTRUMENTATION FOR THE STUDY OF WORKS OF ART G. Chiari, P. Sarrazin, M. Gailhanou
  33. 33. This technique allows for both elemental and mineral phase identification.
  34. 34. Nondestructive evaluation can help us image cultural heritage in new ways. Reflectance & Transmittance Imaging at the Library of Congress Fenella France & Michael Toth
  35. 35. Acoustic Microscopy
  36. 36. Scanning acoustic microscopy (SAM) relies on the propagation of sound waves to create images of materials. Non-Destructive Imaging of Worn-Off Hallmarks and Engraving from Metal Objects of Art Using Scanning Acoustic Microscopy, 2000 PTT Grant, Nelson Atkins Museum
  37. 37. SAM is used to identify worn hallmarks on silver objects. Non-Destructive Imaging of Worn-Off Hallmarks and Engraving from Metal Objects of Art Using Scanning Acoustic Microscopy, 2000 PTT Grant, Nelson Atkins Museum

  45. 45. The nondestructive evaluation industry must be engaged in preservation to find new ways to save our cultural heritage.
  46. 46. Without a technical framework for treatment decision making, conservators and preservationists are left to trial and error.
  47. 47. Nondestructive testing offers new tools to save cultural heritage.
