Testing the Shrinkage Rates of Natural and Industrial Clay

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.


  • 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!
