This video shows how to roll out clay and cut out slabs for a ceramic box. The process applies to other slab clay projects as well. My method minimizes clean up time and makes it easier to leave the space clean for the next class, by the use of plastic mats cut from a roll of shelf-lining material.
This step-by-step demonstration works well for classroom use, and is handy for students who were absent for the 'live' demonstration, and for use with a sub, as well.
The video lasts a little over 5 minutes, but can be paused to check for understanding, etc.
