Ceramics Flashcards
process of forming shapes by pouring deflocculated liquid clay slip into plaster molds for repetitive production
casting
a slab or platform on which clay is handled; a circular device attached to the wheel head
bat
rope like pieces of clay
coil
forcing plastic clay through an auger or form, mechanically or by hand, to change its shape
extruding
typically the second firing of a piece of pottery which has been coated with glass forming materials
glaze firing
usually a plaster form, single or multi-pieced, which will be used to reproduce any number of accurate copies of the original model in clay
mold
moving and shaping clay with the fingers to make a hollow container
pinch pot
quality of clay that allows it to be manipulated dnt still maintain its shape without cracking or sagging
plasticity
roughing up the surface of clay for joining two pieces together
scoring
the method of joining pieces of clay where the two surfaces are scratched up and slip is added like a glue to create a strong, melded bond
slip and score
forming clay on a potters wheel
throwing
it is the kneading or plastic clay in a rocking, spiral motion in order to remove air bubbles and create a uniform consistency
wedging
the device that is used to create pottery using a rotating piece of clay
wheel
construction technique using flat tile like sheets of clay
slab building
clay and water which is used like glue to join clay together is called
slip
this coating makes projects glossy, adds color and makes them waterproof
glaze
clay that has been fired once at a low temperature is called
bisqueware
clay that has not been fired yet is called
greenware
heating pottery to a temperature hot enough to make it hard and durable
firing
the oven or furnace use to fire clay objects at high temperature
kiln
air bubbles trapped in a ceramic project will cause it to _______ in the firing process
explode
large clay projects that are too thick need to be made _______ before firing
hollow
do not glaze the ______ of your projects because they will stick to the kiln shelf
bottom
wet clay will not bond to ____ clay
dry
the protective coating on kiln shelves is called
kiln wash
a dull glaze finished is called
matte
an opaque glaze finish is one that you _______ see through
cannot
base of the pottery that is slightly risen to prevent glaze from sticking to the kiln shelf during firing
foot
clay shrinks at about ___ as it dries
10%
this firing is a preliminary firing to harden clay prior to glazing
bisqueware
liquid suspension of finely ground minerals applied to bisqueware
glaze
the is the stage that is ideal for the first firing
bone dry
the quality which gives clay its unique ability to be shaped and hold its shape after it is formed
plasticity
the condition of raw ware when it is still soft enough to be carved or inscribed or incised
leather hard
clay that has not been fired but is totally dry
green ware
temperature that creates bisqueware
1888° F
temperature that creates glazeware
1945° F
is the process of applying slip in an applicator bottle to draw on a design for a raised effect
slip trailing
objects made of clay fired sufficiently high in temperature for a chemical change to take place in the clay body
ceramics
a brownish-orange earthenware clay body commonly used in ceramic sculpture
terra cotta
fine network of small cracks that occurs on glazes
crazing
these decorations are surface designs cut into clay
inscribing
liquid clay slip that contains coloring oxides and chemicals used to apply color and designs to a ceramic piece
underglaze
clay is hardened by heating it to a high temperature, fusing to clay particles
firing
a triangular support for clay pieces that help prevent glaze from melting onto shelves during a firing
stilt
a mixture of china clay and flint in water solution used to coat kiln shelves to protect them from dripping glaze
kiln wash
best tool to use for incising a ceramic work
needle tool
tool used for inscribing into a ceramic work
stylus
type of table used to drain ceramic molds completely
drip table
cupboard designed to keep projects moist while construction is in progress
damp box
