Mullite is another name for the mineral porcelainite. It is a rare silicate.
Porcelain works by first mixing the clay, kaolin, and mullite and then you woudl put it in a kiln. when it is done you can glaze it or leave it he way it is.
temperatures above 1100 °C kyanite decomposes into mullite and vitreous silica via the following reaction: 3(Al2O3·SiO2) → 3Al2O3·2SiO2 + SiO2
China is made up of these materials; Kaolin, Feldspar, Quartz, and ball clay (petunse). Among these Kaolin is the most component and is white in color however feldspar is the hardest element of all as it is rock but the translucence is brought about by Mullite a rare silicate material Al2O32SiO2 or 2Al2O3 SiO2 which matches with the formula of kaolin AI2Si2O5(OH)4. However Kaolin is soft and usually white and because it contains the Mullite a translucent element it answers your question as it is said to usually be soft this time around it could be hard due to other factors including geographical effects and weather plus time.

Porcelain is a ceramic material made by heating raw materials, generally including clay in the form of kaolin, in a kiln to temperatures between 1,200 °C (2,192 °F) and 1,400 °C (2,552 °F). The toughness, strength, and translucence of porcelain arise mainly from the formation of glass and the mineral mullite within the fired body at these high temperatures.
