This lab activity identifies the salts on ceramic fragments using chemical spot tests and also monitors the extraction of soluble salts through successive water baths using conductivity. Salt deposits can crystallize within porous materials such as ceramics. This process causes damage known as flaking or spalling, which can destroy object surfaces. Identifying the salts present in an artifact is vital for determining the course of treatment. If the salts are identified and characterized as soluble, one of the most common treatment procedures is to soak the artifact in distilled water. Conservators monitor the treatment progress by measuring the conductivity of the successive water baths. This experiment uses chemical spot tests to discover the chemical formula of a salty build-\u00ad\u2010up on ceramic material. The second half of the experiment investigates conductivity and how the practice of bathing ceramics works.\u00a0<\/span><\/p><p><span style=\"font-size: 12pt\"><strong>Objectives:<\/strong><\/span><\/p><ul><li><span style=\"font-size: 12pt\">Identify the unknown ions present<\/span><\/li><li><span style=\"font-size: 12pt\">Predict ionic compound formulas<\/span><\/li><li><span style=\"font-size: 12pt\">Observe changes in conductivity levels<\/span><\/li><li><span style=\"font-size: 12pt\">Graph conductivity data<\/span><\/li><\/ul><p><span style=\"font-size: 12pt\"><strong>Georgia Performance Standards:<\/strong><\/span><\/p><p style=\"padding-left: 40px\"><span style=\"font-size: 12pt\"><strong>SB1.<\/strong> Obtain, evaluate, and communicate information to analyze the nature of the relationships between structures and functions in living cells.<\/span><\/p><p style=\"padding-left: 80px\"><span style=\"font-size: 12pt\">d.
