Today, we began our investigation into the shrinkage rates of natural and industrial clay. Our objective is to use the information gathered from this study to create a PCB cast for ceramics. We will be comparing the shrinkage rates of the two types of clay to design a cast that can accommodate different types of clay.
Methods:
- Obtained samples of natural and industrial clay
- Measured out equal portions of each type of clay
- Allowed the clay to air dry overnight
- Fired all samples in a domestic oven
- Fired all samples in an industrial kiln
- Measured shrinkage rates and compare
Next, we will be measuring the dimensions of the dried clay to determine the shrinkage rate. Excited to see the results!
