This presentation provides an inorganic chemist's perspective on metals used to make organ pipes and their corrosion and conservation. The slides highlight my own research in this area as well as work being done by other scientists around the world. The purpose of this learning object is to show students an application of inorganic chemistry that they probably have not encountered before and show an example of how analytical methods of materials chemistry can be used in conservation science.
The Power Point presentation contains nine slides, including the title slide and a slide with additional references. The Word file containing accompanying notes provides background information corresponding to each slide.
1. A student should be able to identify the material that is most commonly used to make organ pipes.
2. A student should be able to describe the chemical process through which atmospheric corrosion occurs.
3. A student should be able to give examples of experimental methods that are used to study organ pipe corrosion.
This learning object is part of a lecture I have developed on inorganic chemistry in art conservation. Each year, I devote the final class of the semester in my sophomore/junior-level inorganic chemistry course to this topic. I briefly introduce some ideas about conservation science and then present several case studies showing questions about artifacts or problems of deterioration that have been addressed through scientific analysis. These include studies of paint discoloration on a portrait and the conservation of a wrecked ship as well as my work on organ pipe corrosion. I intend this last-class lecture to be interesting and enjoyable, and I let students know that I don't expect them to take in all the details as they might in a normal lecture. I do point out that during the lecture, we'll briefly touch on and review many inorganic chemistry topics from the semester.
Information about the other case studies and the introduction to conservation science are to come in future "Five Slides" installments!
