6. Test for fired water absorption
The degree of water absorption is the measure of the vitrification of a fired clay body. This is determined by the following procedure
- Make bars of 5X5X10 cm. Minimum 3 bars has to be made.
- Fire the bars and weigh the fired bars.
- Boil the fired bars in water for 2 hours.
- Dry the surface of the bar with a towel and weigh them again.
- Calculate the water absorption by using the following formula.
% Linear Water Absorption = ((Saturated Wt - Dry Wt)/Dry Wt)*100
