The formation of color in ceramic glazes can often be influenced by the firing conditions. In an oxidative firing, copper ions present give a green-to-blue glaze. Under reduction conditions, the copper ions in the glaze provide a reddish color. Metallic ions with multiple oxidation states thus enable potters to achieve a great variety of colored glazes. Other redox tricks will also be discussed.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
