Cork is derived from the thick bark of cork oak trees. Every nine years, the outer layer of the bark can be harvested. As a renewable resource, cork is more eco-friendly than wood because it takes less time to grow and the trees do not need to be cut down.

Cork is resistant to moisture due to a particular waxy substance called suberin that coats its bark. Also, within the suberin, there is a special substance called the Casparian strip, which is a natural pesticide. Thus, cork is a particularly unique material in that it can naturally resist moisture, decay, and worms.

Despite the advantages of cork as a material, its uses have been limited. Through Corker Collection project, Yuting Chang introduces the usage of cork into everyday objects in the hopes of inspiring others to use this eco-friendly material in innovative ways.
