Abstract
The melting of glass depends on the generation of high
temperatures and suitable containers for the molten glass.
Attempt is made to develop these containers for molten glass
from local refractory clay materials comprising of Kaolin
from Kankara Katsina State whose deposit has been found to
be of economic value and ball clay from Bomo-village -
Zaria, Kaduna State. Five different composite bodies were
prepared from the local clay materials, and have been used
to cast refractory pots which were fired and tested for the
following properties; (i) Refractoriness (ii) Thermal Shock
resistance and (iii) Resistance to chemical attack by molten
glass.
All pots made were able to withstand high temperatures
without crumbling although some showed higher crack
formation. The refractory pots were able to withstand the
chemical action of the molten glass of lead crystal and
soda-lime silica glass batches. The composite body of 60%
grog and 40% Kaolin was found to be the most suitable for
the production of pots that would be used for melting glass,
having showed the best results of the tests that were
carried out, thus it is being recommended for the production
of refractory pots for melting glass.
