ornamental or functional

, and has been widely employed across cultures

   For

archaeologists, anthropologists and historians

the study of pottery can help to provide an insight into past cultures. Pottery is

durable

, and fragments, at least, often survive long after artifacts made from less durable materials such as grasses, bone, or glass decayed or been distroyed past recognition. Combined with other evidence, the study of pottery artifacts is helpful in the

development of theories on the organization, economic condition and the cultural development of the societies

that produced or acquired pottery.

Pinch pot vases are reasonably simple to make and so, are a great beginning project. These vases incorporate the pinch pot method and scoring and slipping with additive features.

Continued Impressive Pinch Pot Vases    Students learn the parts of a vase , devise five types of their own creation drawing them as thumbnail sketches before they are given clay , and produce at least three of their ideas.

Designs are impressed, or stamped into two separate clay buttons for two sides of the pot.

Finally, students will test different glazes on the vases.

    Familiarity with the medium one is working with is important in the creation of art.

Students will understand and practice manipulation of the type of clay available to them. Students will discover and perfect basic construction methods and decorative methods, as well as observing the qualities of basic commercial glazes over textured and smooth surfaces. This is also a good time for students to learn how to set up, put away, and properly use the equipment, materials, and tools they need to create their products.

Here are some pointers for creating pinch pots:

 work in a spiral from bottom to top  use the tip of your thumb on the interior , while supporting the exterior with your other hand  minor stretch cracks can be left as a textural effect, if desired  deep cracks should be welded immediately using a tiny amount of slurry or slip  rims can be left untrimmed or they can be trimmed with a potter's needle when the pot is leather hard  the pot can be smoothed , or even burnished with a wooden rib, when the pot is leather-hard

Taking a Break

Pinched forms can take more time to create than we have in one sitting. When you have to leave your work while it is in progress, place damp paper towels across the top row. Cover the entire piece with plastic.

If you should need the bottom of the pot to stiffen slightly, leave some gaps where the plastic meets the table or shelf. Otherwise, tuck the plastic under the support surface. If the humidity is high, add a layer of newspaper or cloth in between the pot and the plastic. This will absorb any condensation, which could otherwise make your pot collapse.

Wax Resist

  

Definition: Wax Resist (noun) is a waxy substance

used to prevent slips or glazes from adhering onto the clay body or a prior coating of slip, etc. A resist is especially helpful in keeping glaze from adhering to a pot's base, and in the case of a lidded jar, from keeping the areas the lid and the jar meet free from glaze.

In the past, wax resists where simply melted wax; today there are a number of wax emulsions, including many which are water-based.

Wax resist can also used in decoration. The resist can be used both under or over underglazes, glazes, and slips to create designs.
