A high fired clay pot is waterproof and a glazed pot is waterproof and both are safe for this purpose.
by bisk firing clay and then glazing it and firing it again, the clay will become waterproof. the clay hardens and the glaze (once heated)and becomes just like glass covering the outside of the clay.

You can buy some clay or flatten it out a lot! That is how you can make clay bigger. Adding water to clay makes it bigger. In dry season, you can see cracks in the clay where it has shrunk.

Clay makes bricks. Sand is used in cement.
Terracotta is fragile, because it must be made thin. It is made as thin as possible to prevent an artist leaving air bubbles inside of the clay. If there is air inside of the clay it will expand and break the clay while it is being fired.
