Pinching
Pinching is a method where the potter starts with a ball of clay and uses their fingers to pinch and form a pot. It allows for delicate shapes and is good for making small vessels like bowls and cups.
Burnishing
Burnishing is the technique of polishing leather-hard or dry clay to create a smooth, shiny surface. A stone or a spoon can be used to rub the surface until it becomes shiny. It's often used in pit firing to produce a glossy finish without glaze.
Mishima
Mishima is a technique where incised lines are filled with contrasting colored slip or underglazes and then the surface is scraped to reveal a clean line. It's used for intricate designs and fine line details on pottery.
Nerikomi
Nerikomi is a decorative process that involves stacking and slicing colored clay to create patterns that run throughout the clay body. It's similar to the millefiori technique in glass-making and is used for intricate patterns.
Agateware
Agateware is pottery made by mixing differently colored clays or by layering colored slips to create a marbled or swirled effect, which resembles the natural stone agate. It's used for decorative objects and tableware.
Raku Firing
Raku firing is a rapid, low-temperature firing process. The red-hot pottery is removed from the kiln and subjected to post-firing reduction (or smoked) in containers of combustible materials. It creates unique patterns and colors.
Sprigging
Sprigging is attaching small, molded pieces of clay (sprigs) to a wet or leather-hard clay body. It's primarily used for decorative elements and adding relief designs to the surface of pottery.
Slip Trailing
Slip trailing is the application of slip to a clay body through a nozzle or syringe to create raised designs. It's often used to decorate pottery with lines, dots, and other patterns before firing.
Throwing
Throwing is the process of shaping clay on a potter's wheel. The clay is centered on the wheel head and formed into a vessel by the hands as the wheel spins. It's commonly used for symmetrical pieces.
Coiling
Coiling involves rolling out long, snake-like ropes of clay and stacking them to create a vessel. The coils are blended together to create walls. This technique is often used for hand-building pots without a pottery wheel.
Chattering
Chattering is a technique used on leather-hard clay where a tool bounces or vibrates against the wheel-thrown pot to create a rhythmic pattern. It creates textured surfaces and decorative effects.
Underglazing
Underglazing is applying colors to a bisque-fired ceramic piece using materials that won't blend or bleed when a clear overglaze is applied. It allows for detailed painting and decoration beneath the protective glaze.
Slip Casting
Slip casting is a method where liquid clay (slip) is poured into a plaster mold. The plaster absorbs the water from the slip, creating a cast clay object. It's often used for duplicating items and mass production.
Lustre Glazing
Lustre glazing is the application of a metallic glaze that, when fired, creates a shiny, iridescent finish on ceramics. It's used to add a luxurious, often gold or silver, appearance to the pottery.
Wedging
Wedging is a kneading technique used to homogenize the clay, removing air bubbles and ensuring consistency. This preparation step is necessary before throwing or hand-building with the clay.
Slab Building
Slab building involves rolling out flat pieces of clay (slabs) and joining them together to form objects. The edges are scored and slipped to ensure a strong bond. This technique is used for making angular shapes and larger items.
Sgraffito
Sgraffito involves scratching through a layer of slip or underglaze to reveal the clay body beneath. It's used for decorative surface techniques and creating contrasting images or patterns.
Salt Glazing
Salt glazing is a technique where salt is introduced into the kiln at high temperatures. The salt vaporizes and reacts with the silica in the clay to form a shiny, textured glaze. It's often used for stoneware.
Carving
Carving is removing clay from a leather-hard piece to create a design. This subtractive method can add depth and texture. Carving is often used for detailed decorative work and relief designs.
Cuerda Seca
Cuerda Seca is a decorating technique involving creating a 'dry line' by applying a mixture of wax and black manganese to separate different colored glazes. It is used to prevent glazes from bleeding into each other.
