Porcelain is a ceramic material made by heating selected and refined materials, often including clay in the form of kaolinite,|
to high temperatures. The raw materials for porcelain, when mixed with water, form a plastic body that can be worked to a required shape
before firing in a kiln at temperatures between 1200°C and 1400°C.
The toughness, strength, and translucence of porcelain arise mainly from the formation at high temperatures of glass and the mineral
mullite within the fired body.
Porcelain was named after its resemblance to the white, shiny cowry, called in old Italian porcella (little pig),
because the curved shape of its upper surface resembles the curve of a pig's back.
Several porcelain dice with sizes between 16 and 25 mm,|
most of them marked with 'JAPAN' on the '1' side (hardly visible on the pictures).
Two sets of old porcelain dice for the Dutch game 'Boerenschroom' (translated in English as 'Peasant's fear').|
This game was played in the 19th century in the Netherlands using 8 cards and 2 dice: one die with the markings
B,1,2,3 and the other die with the markings S,4,5,6.
Nowadays the game is hardly ever played anymore.
