Quality
Control Process
Raw Materials
Visual inspection for any dust or foreign materials specially free iron.
For ensuring good quality we conduct
Firing Test in which powder
sample is taken and fired for color and fluidity.
Quartz
Visual inspection for any dust or foreign materials especially free iron.
For ensuring good quality, we conduct
Firing Test for color and
liquidity.
Clays
We carry out several tests for each lot such as
grit content on 300
mesh,
dry shrinkage, fixed shrinkage, free moisture content and
fired
color.
Coloring Oxides
(Iron, Chrome & Maganese) 1% of the oxide (under test) is to be mixed
with white glaze and compared with standard oxide. Now both the samples are
fired under identical conditions. Identity of the color to be compared.
Body
Several tests carried out during and after the formation of the body such
as residue of every discharge,
green shrinkage, firing shrinkage,
porosity and
green strength at different time intervals.
Glaze
Various tests are conducted during and after the formation of the
glaze
such as
testing the residue, flow of glaze and
fire test.
