What is the purpose of darting in ceramics?
Problems can appear in many forms if drying is not done uniformly. Cracking due to shrinkage can be a major issue, especially in parts that vary in thickness. All ceramic products also shrink when fired. Drying and pre-firing ceramics help aid in the amount of shrinkage that occurs to the end product.

Why is clay shrinkage important?
Why does clay shrink? Clay shrinks both during the drying process and the firing process. Shrinkage in the drying process occurs due to the loss of water layers. The finer the particle size of the clay, the more water layers; hence the more shrinkage.
What is bisque firing?
Biscuit (also known as bisque) refers to any pottery that has been fired in a kiln without a ceramic glaze. In situations where two firings are used, the first firing is called the biscuit firing (or “bisque firing”), and the second firing is called the glost firing, or glaze firing if the glaze is fired at that stage.
What are the purposes of drying ceramic products before firing?
Prior to firing, ceramics often are heat-treated at temperatures well below firing temperatures. The purpose of this thermal processing is to provide additional drying, to vaporize or decompose organic additives and other impurities, and to remove residual, crystalline, and chemically bound water.
What is feldspathic glaze?
Feldspathic glazes of porcelain. Lead glazes, plain or coloured, are shiny and transparent after firing, which need only about 800 °C (1,470 °F). They have been used for about 2,000 years in China e.g. sancai, around the Mediterranean, and in Europe e.g. Victorian majolica. Salt-glaze, mostly European stoneware.
What are clay tools called?
There are pottery tools specifically designed for ceramics. Among these are: elephant ear sponges, potter ribs, loop tools, needle tools, fettling knives, and toggle clay cutters. Other essential ceramic tools are the elephant ear sponge and potter ribs.
Can you make pottery at home without a kiln?
A Kitchen Oven This is the most modern method of firing ceramics without a kiln. The low temperatures can also mean that only certain types of clay (such as salt dough) will work when fired in a domestic oven, and even then the finished product may be brittle.
What are the materials used to make pottery?
Common examples are earthenware, stoneware, porcelain, and bone china. Clay is one of the widely available raw materials for creating ceramic objects. Different types of clay and combinations of clay with different variations of silica and other minerals result in different types of ceramic pottery.
What is pottery made from?

How do you stop a teapot from dribbling?
The authors suggest that one way to avoid dribbling is to make the lip of the spout as thin as possible (as in metal teapots, which rarely dribble), while the ultimate way to instantly stop dribbling and end the teapot effect for good is to use a thin, sharp-ended spout and coat the lip with one of the latest super- Nov 2, 2009.
Why do spouts dribble?
In physics jargon, at higher flow rates, the layer of fluid that is closest to the teapot’s spout detaches so it flows smoothly and doesn’t drip. At lower flow rates, when flow separation occurs, it reattaches to the spout’s surface, resulting in a dribbling flow.
How do you make a teapot spout?
Why is it important to wedge clay?
Wedging prepares the clay for optimal use. Wedging makes the clay more pliable, ensures a uniform consistency, and removes air pockets as well as small hard spots in the clay before you use or reuse the clay for a project. When reclaiming clay, wedging ensures all the clay is incorporates together.
What is the drying shrinkage?
Drying shrinkage is the contraction in the concrete caused by moisture loss from drying concrete. Shrinkage-compensating concrete is used to minimize cracking and structural movement caused by drying shrinkage in concrete.
