Ceramic Glaze is a form of glass, comprised of oxides and minerals combined with water. The different oxides and minerals react when heated to provide an infinite variety of colours, textures and finishes. Glazes are often commercial produced, although many ceramic artists create their own to provide unique effects. Glazes can be applied in an endless number of ways - dipping, spraying, brushing, pouring, layering, etc.
The general name given to a colour range of subtle green to blue-gray stoneware and porcelain glazes, deriving from iron in reduction.
The Japanese name for very dark coloured high iron glaze which in reduction yields a near-black. The glaze "breaks" to an iron-red or brown on the high points.
Literally to scratch or scrape. Often refers to the removal of one layer of slip or glaze to reveal another. But can refer to any procedure whereby a clay piece is scratched or scraped.
A common technique that uses pre-moulded shapes pressed into wet clay to create an inverted image of the mould on the object. Often, the objects are made of Bisqued clay and some form of anti-bonding agent is used to prevent the object from sticking to the wet clay
A common technique in building clay objects which involves adding details to a still-wet object. Often, the additions are adhered to the object by "slipping and scoring" where either water or slip is used, along with shallow scratches on the facing elements of the object and the addition.
An inlay is a method of glazing where an incised pattern or design is painted over with glaze to fill the incisions. Once dry, excess glaze is scraped away to leave only the glaze caught in the grooves of the pattern.
Slip is clay that has been diluted with water. Sometimes, minerals are added to slip to give it colour when fired. Slip is used throughout ceramic art and has many pivotal applications like decoration, as an adhesive agent and can even be used to dip a form in to create thin, delicate clay objects.
