Hi, I am Tamal Bhattacharya talking on behalf of Expert Village. Subject is terra cotta
mural. The processing of the clay is very important in terra cotta mural. Two ways of
processing, traditional way and casting process. Traditional process is the old process; casting
process is a modern process. We have formed a design inside. It has two different parts,
easy to open it up. This is a rubber band, it will hold these two parts tightly and temporarily.
You'll see, inside this cast there is a complete design. Now we are going to pour liquid clay.
After a few minutes, the plaster mold absorbs the water so we need to pour mud again and
again until it comes up to the thickness. After a few minutes we discharge the excess
liquid clay. Cure the mold for half an hour. Now it is ready to open it up. How much time
this liquid clay takes to harden depends upon its mass and volume. This completes the casting
process. You see the complete design. This is the casting process. Thank you.
