A term that describes all unfired clay. This includes clay that is wet, leatherhard, and bone dry.
What is Greenware
100
A glass coating on the outside of a ceramic piece.
What is Glaze?
100
Things we use in ceramics to measure and gauge the amount of heat inside a kiln when firing.
What are pyrometric cones?
100
This term is used to describe the clay reproduction created from your mold.
What are Casts?
100
This is the first step when working with clay using any process.
What is Wedging?
200
A type of Clay Deposit that is eroded directly beneath its parent rock.
What is Primary Clay?
200
A material that with stands melting at high temperatures.
What is a refractory material?
200
This is the first firing in the ceramic process that drives off all physical and chemical water. During this firing clay becomes hard and turns into rock. After this firing the ceramic pieces can be handled without breaking and glazed.
What is a bisque firing?
200
The two main types of colorants used in ceramics.
What are metallic oxides and mason stains?
200
This is what we do when attaching two pieces of clay together.
What is slip and score?
300
A type of Clay Deposit that is eroded further from the parent rock. This contains other impurities such as metallic oxides and other biological material.
What is Secondary Clay?
300
This material is the glassmaker in a glaze.
What is Flint or Silica?
300
This is a firing range typically used for earthenware clays and is at a lower temperature.
What is Low-Fire? (cone 04)
300
A kiln commonly fired to a High-Fire temperature range. This is used to glaze fire clay bodies like stonewares and procelains.
What is a gas kiln?
300
The process of attaching flat planes of clay together to construct a form.
What is slab-building or slab construction?
400
The processes of erosion through which clay is made.
What is Kaolinization?
400
A material that lowers the melting point of other materials around it. These are used in ceramics to lower the melting point of silica in a glaze.
What is a flux?
400
A firing range used for glazes on porcelain and stoneware clays and is at the highest temperature range.
What is High Fire? Cone 10
400
A coil of clay with at least three pyrometric cones used to determine how much heat is in a kiln.
What is a cone pack?
400
The first step in wheel throwing before you make a hole in your clay
What is centering?
500
This characteristic of a clay body describes the ability to bend and manipulate the clay without cracking.
What is Plasticity?
500
The roll of Alumina (clay) in a glaze? This helps keep melting silica from running off of the surface of a ceramic piece during a firing.
What is a stabilizer?
500
This type of kiln is used when you fire to a low-fire temperature and you open the kiln to remove the pieces when the kiln is glowing hot.
What is a Raku kiln?
500
Three characteristics of a clay body.
What are Texture, Color, Maturation point (temperature), plasticity (workability), Shrinkage?
500
This is the type of tool used to smooth out the surface or shape a pot while throwing on the potter's wheel.
