Abstract
Four clays from Madras State have been studied. All th,e clays a;re kaolinitic.
The clays also contain ferruginous impurities and develop varying degrees of buff
colour on firing. While the clays have high refractoriness and refractoriness underload,
they have poor bonding strength in the fired state. In gen;era~, the clays are
very promiszng as raw matenals for manufact,ure of fire clay r~fractories; one .of
tJhe clays has a high silica content and may also prove useful for making semi-silica
r,efractories.
