What is stoke China and what kinds of slipware are there. The latest edition of the Dinnerware Ceramics Glossary. The letters S to U.

Sagger

A container made of fireclay into which the pottery to be fired is placed. The sagger protects the pottery from the flames and gasses inside the kiln during firing. By stacking the saggers inside the bottle kiln it was possible to load thousands of plates into the kiln at once.

Saltglaze

Staffordshire white or cream stoneware with semi-shiney by throwing rock-salt into the kiln at its peak temperature. The salt disassociates into sodium and chlorine ions at the oven temperature thus allowing the sodium to combine with the silica in the clayware to form a glaze that makes the ware non-porous.

Satin Glaze

A glaze with medium reflectance. The glaze is between matt and gloss.

Sgraffito

Style of slipware where a slip coat is used which is of a different colour to the body of the pot and is then decorated by cutting a pattern through the dry slip coat to reveal the contrasting colour of the body of the pot beneath.

Slab

Pressed or rolled flat sections of clay. They are used in building ceramics by hand.

Slip

Clay mixed with water, into a liquid, sieved to remove any particles. Slip is made as a means of accurately mixing the ingredients of a pottery body or to be used for casting ware in plaster moulds.

Slip casting

Casting with liquid clay.

Slipware

Pottery, usually earthenware, whose decoration is based upon the use of slip.

Slurry

A thick slip.

Soaking

Maintaining a low steady heat in the early stages of firing. The goal is to achieve a uniform temperature throughout the kiln.

Sprigging

Applying pre-molded relief motifs to the surface of a pottery object and connecting them by curled stems formed of threads of thinly rolled clay.

Spur

A triangular support used to separate plates within the sagger during firing in the kiln. The use of spurs can leave small spots on the surface of the plate. Usually three sets of three spur marks can be found on the underside of the rim and a single spur mark can be found on the upper side of the rim.

Stacking

Load a kiln to hold the maximum number of pieces.

Stain

Oxide and water, used as a colorant for bisque wear.

Stipple punching

An engraving technique where small dots are used to fill larger regions of a transfer ware pattern. The dots are created with a sharp punch that is driven into the copper plate.

Stoke China

Josiah Spode used this name for English bone china.

Stone China

Pale grey, fine porcelainous stoneware that is hard, dense and sometimes translucent. John and William Turner developed it in 1800. Miles Mason and Josiah Spode reintroduced it around 1812.

Terracotta

Unglazed porous earthenwares.

Throwing

Creating ceramic shapes on the potter’s wheel.

Throwing

A method of shaping holloware. A ball of clay is thrown onto a revolvong potter’s wheel, is centred and then shaped by the hands.

Transparent Glaze

Transmits light clearly.

Tyg

A drinking vessel with more than two handles or two set close together.
It is said to have been used in Staffordshire as another word for porringer, but its use to denote taller drinking vessels with several handles has not been traced further back than the nineteenth century.

Under-glaze

Decoration of ware before glazing and being fired.
