Product Information
Thousands of years ago, before people knew about advanced concepts in chemistry, dyes and pigments were extracted from natural materials.
Science teacher David Budnik developed this hands-on kit that lets students extract their own dyes from plants. Students can make red, yellow and brown dyes; use these dyes on fabric samples; then study the results of the dyes both with and without mordants (metal salt solutions used to ensure colorfastness).
Includes materials for nine student groups and instructions.
