There will be an upcoming quiz over the following terms:
Slip – A mixture of mostly water and clay.
Plastic Stage – When clay is very soft and stretches without
cracking.
Leatherhard Stage – The best stage to attach pieces of clay
together- the clay is firm, but carvable.
Greenware Stage – Also known as “bone-dry”; clay cannot be
worked at this point.
Bisqueware – clay has been fired once. It has been
permanently changed and cannot be reclaimed. This stage is when you apply
glaze.
Glazeware – After the clay has been fired the second time
and the glaze has turned to a finish.
Glaze – This is applied to a piece of bisqueware and then
fired to create a glossy or smooth surface to a ceramic piece.
Kiln – A piece of equipment that is used to heat clay to a
high temperature; the clay becomes very strong and permanently changed from the
heat.
Wedging – similar to kneading dough; this process works out
air bubbles and creates a consistent clay body. It can also be used to remove
excess moisture from clay.
Scoring/Slipping – This technique is used to attach two
pieces of clay together. First you scratch each piece of clay where they will
connect, then you apply this liquid clay solution to ensure the pieces stay
together.
Coil method– A way of handbuilding that involves rolling out
thin long pieces of clay and spiraling them up to form a vessel.
Pinch method – a way of handbuilding that involves gently
and continuously pressing your thumb on the inside of a ball of clay with your
fingers cupped around the outside.
Slab method- a method of handbuilding that can be done with
a rolling pin; you roll out thin sheets of
clay and cut them into sections to create sections of the vessel.
Potters Wheel – a device used to create clay pots that can
spin at very high speeds.
Bat – A wooden or plastic disc or square that clay is placed
on while working on a project.
Reclaim – the process of taking unwanted greenware, slip, and
very dry clay and returning it to a consistent plastic stage clay body.
