Hard-paste porcelain

Hard-paste porcelain is a "hard" (hot) fired porcelain .

In contrast to soft porcelain, it is created through higher firing temperatures (1400 ° C to 1460 ° C) and is largely insensitive to temperature fluctuations. It consists of 47–66% kaolin , up to 25% quartz and up to 25% feldspar . The relatively high proportion of kaolin gives the finished product a comparatively higher impact resistance.
