The factors likely to affect the end properties, especially the fired strength
of heat insulating bricks made by the soft-mud process were studied. Rajhara fire
clay was found to be most suitable in developing the strength of these bricks.
Forming pressure rather than the firing temperature was found to affect the strength.
The stT'ength also appreciably improved on increasing the clay content from 40 to
45%, adding 2.5% bentonite or on slightly increasing the fineness of mica used.
