Fired shrinkage is 10.5% and water absorption is 0%.  Slightly course.  This clay is lightly grogged with no sand and has shown to do really well with both hand built and thrown ceramic wares.  Fires to a bluish color in bisque.  Deep black at cone 10.  Black clays can affect glazes, so testing will be required.  Bloating has not been an issue with this clay.
