The Teas Chart
Conservators use a variety of solvents to remove adhesives and clean many types of materials. The Teas chart is one of the ways of categorizing solvents. It is mainly empirical, but seems to work and is relatively easy to understand.


After completing this tutorial, you will be able to:

• Describe the types of intermolecular bonding that are affected by solvents
• Understand the contribution of electronegativity to bond polarity and intermolecular bonding
• Use references that list the Teas fractional parameters to place the solvents on a Teas chart
• Use a Teas chart to aid in selecting appropriate solvents for specific applications
