Conservation Conservators Science Science Series Teaching - HOME Conservation Conservators Science Science Series Teaching Archaeological Conservation Using Polymers: Practical Applications for Organic Artifact Stabilization by C. Wayne Smith, Over the years, archaeologists have developed a number of techniques for conserving historical artifacts for future generations. Up to now, however, these methods have provided artifacts only a limited lifespan and in some cases they do not work well with water-logged materials. Within the past few years, archaeological chemistry and concerns of longevity testing have become central issues in the development of conservation treatment strategies. This problem became particularly acute when ...

Chemistry Health Science - HOME Chemistry Health Science Chemistry and Life: An Introduction to General, Organic and Biological Chemistry by John W. Hill, What is chemistry? Chemistry is such a broad, all-encompassing area of study that people almost despair in trying to define it. Indeed, some have taken a cop-out approach by defining chemistry as "what chemists do." But that won't do; it's much too narrow a view. Chemistry is what we all do. We bathe, clean, and cook. We put chemicals on our faces, hands, and hair. Collectively, we use tens of thousands of consumer chemical products in our homes. Professionals in the health and life sciences use thousands of additional chemicals as drugs, antiseptics, or reagents for diagnostic tests. Your body itself is a remarkable chemical factory. You eat and breathe, taking in raw materials for the factory. You convert these supplies into an unbelievable array of products, some incredibly complex. ...
