    Gaolin Mountain

    The traditional source of Kaolin clay used in Chinese porcelain is Gaolin mountain.  There’s actually not much to see at the park there- all the kaolin clay was mined out a very long time ago.  But the mountain itself is beautiful, and the nearby villages still offer a glimpse into “old China”.

    Although there’s not much to see related to ceramic history, the mountain is beautiful.

    The old village is quaint and peaceful.

    Traditional houses are found in the smaller villages around Kaolin mountain.

    Natural Quarts and Mica additions to porcelain

    Test of adding natural quartz and mica to porcelain.

    Porcelain is Taida 609 fired to 1310 celsius in reduction.

    Top row: 5, 10, 15, 20% addition of silica to 100g porcelain slip
    Bottom row: 5, 10, 15, 20% addition of mica to 100g porcelain slip

    The natural quartz has a ton of impurities. Also I did not consistently grind or filter the quartz. Addition of quartz impedes translucency.

    I’m not sure exactly what type of mica I used. However, it seems pretty clean and of uniform particle size. Didn’t notice translucency affected much. The last tile is a little thicker than the others so appears more opaque.
