Yep, Kingery is worth reading. Also Linus Pauling's "The nature of the
Keep in mind that green ware still has about 10 % water adsorbed on the
clay and other particles. Mostly the particles are held together by van
der Waals bonding. There also is significant ionic bonding between various
edges of the crystalline particles in the clay body.
