Seite 696 - There are two methods of quantitatively analyzing clays. One of these is termed the ultimate analysis, the other is known as the rational analysis. The ultimate analysis. — In this method of analysis, which is the one usually employed, the various ingredients of a clay are considered to exist as oxides, although they may really be present in much more complex forms. Thus, for example, calcium carbonate...
Seite 721 - King-techin porcelain is made, is not true kaolin, but a hard jade-like greenish rock which occurs between beds of slate. He states: 'This rock is reduced, by stamping, to a white powder, of which the finest portion is ingeniously and repeatedly separated. This is then moulded into small bricks. The Chinese distinguish chiefly two kinds of this material. Either of them is sold in King-te-chin in the shape of bricks, and as either is a white earth, they offer no visible differences.
