| Abstract |
| The essential requirements of refractory clays for satisfactory
application in pot making are considered to be
bonding characteristics and wide vitrification range apart
from adequate refractoriness. In the absence of a comprehensive
information on the availability of typical pot
clays in India, and in view of the need for improving upon
the performance of ceramic pots wherever these are deployed
for glass melting, some of the clays from different
sources in the country have been investigated for relevant
physico-chemical characteristics and with respect to
attainment of suitable properties vis-a-vis optimisation of
variables in processing and fabrication. The results have
been tabulated for comparison. Several compositions of pot
mixes through adjustment of proportion of grog and
gradings thereof have been evaluated for characteristics
with a view to ascertaining the most appropriate requirement.
Minor additions were tried to adjudge their role
thereof towards improvement. A blend of clays that may
provide satisfactory performance, if processed with care
in different modes of fabrication, has been indicated. |
