Variations
With slip casting,
the water is completely absorbed into the mold, whereas in drain
casting, the slip may removed after a predetermined thickness
of ceramic has been deposited onto the mold's walls.
Continuous Tape Casting
Also known as blade
casting. The slip is cast onto a moving, flat surface and scraped
down to a thin layer with a squeege-like blade called a doctor
blade. This result is sheets of ceramic with a very accurate
thickness.
Pressure Slip Casting
The
advantage of this type of slip casting is that the pressurized slip
adheres to the walls of the mold more evenly and with fewer defects
than with traditional slip casting. This is being researched by
Dr.
Hans-Jürgen Richter.
