| Abstract |
| Fusible Clays
Fusible clays generally fuse and lose their
shape at relatively low temperatures. Some of
~hese clays do not melt completely below porcelain
heat and are useful in making common
pottery and tiles whereas the most common
varieties are used for making common bricks.
These clays generally contain rather a large proportion
of silica, mostly in free state, beside
fluxes, like lime, iron, soda and potash. These
substances combine at a dull red heat, forming
fusible silicates which melt down when heated to
higher temperature. |
