Acknowledgments
I would like to thank several people for their assistance throughout the production of this
thesis. First I acknowledge my advisor, Frank G. Matero, who has provided invaluable
wisdom and direction in all aspects of the research. His enthusiasm for this project was
instrumental in guiding my work. I thank Dr. A. Elena Charola for her assistance with
the statistical analysis which enabled me to confidently interpret the results of the
laboratory tests. For his careful reading ofthe final draft, 1 thank Sam Harris.
Much ofthe background research involved interviews with architectural conservators and
architects who have previously attempted to solve the problems investigated in the
present study. For taking the time to discuss their experiences with me, 1 thank John
Fidler, Ricardo Viera, Joel Snodgrass, Theodore H. M. Prudon, Deborah Slaton, Carolyn
L. Searls, Karen Reed, Dale Frens, Cathy Carosino, and Michael Edison.
In addition, I would like to thank Rich Smitheman of Joseph Dugan Contractors and
Watson & Henry Associates for providing me with pieces of glazed terra cotta from the
Ventnor City Hall, without which the experimental program would not have been
possible. A stipend awarded by the National Council for Preservation Education,
National Center for Preservation Technology and Training, and the National Park Service
provided funding for the preparation ofthese pieces for testing.
wholeheartedly thank my parents for making my education possible and for providing
I
me with much needed perspective throughout my studies. Finally, 1 thank my fiance,
Richard Effress, for his unconditional support and encouragement.
